Want to buy the large super neodymium magnets?That is hard to find a good supplier for that. So in this article, we will help you how to get big size magnet supplier, no matter you want big N35 neodymium magnet, N48 , or N52 huge neodymium magnet.

Where to buy it.

You should find it in China.  China suppliers have applied outstanding quality, innovative magnetic design and advanced manufacturing to help their customers succeed. Lots of them ensure long-term reliability and quality with the vertically integrated approach. They will help you in solving the design challenges and also it identifies the best and the top quality materials for the target application. Most of them have expert capabilities that enable the customers to meet their needs with their involvement in machining, assembling, designing and testing the client’s products.

For thousands of years, the magnets were used only as compass needles and toys in China. But since the advent of the electronics, the magnets have found their application in many of the everyday objects. In the 20th century beginning, many unique advances were made in magnetic materials. Now, the magnets are used widely in the speakers, hard drives, turbines, electric motors, Nuclear Magnetic Resonance, cathode ray tubes, transformers and more. As we know, China is the world factory,  they produce and sell these products all over the world. So you should believe they have well experience in produce big size magnet.

Large size magnet material is hard to find

Not every magnet factories can make big size neodymium magnet. The first point is, you should know where to buy the big size material. If you ask some regular factories for the big size. They will reject or offer you a crazy price. Because they need to takes time to check with the material supplier.  That is a big work.  70mm material is an easy find. 200mm magnet will be very difficult. 250mm, some suppliers tell that it is an impossible mission.

Why large size neodymium is hard to process

Even you find the material, processing will be another problem. Because not all machines can handle it. Lots of regular factories just can operate magnet which is smaller than 60mm. If over that, they have to buy a new machine to process it.  Even you have a machine to process it, you still need an experienced worker to do it. That is important. Without a skilled engineer, even packing the magnet will be a big problem. As you know such big size magnet will get very big power. That is a big risk. Just like Halbach Array,even that is small set Halbach array, still difficult to assemble. That needs lots of skilled engineers to deal with it.

As we discussed, if you want a big size custom neodymium magnet what you need are :
1. big size magnet material
2. the machine can process big size magnet
3. Skilled engineer

That is the main factors, but still has some technical limit,you should know:
1.Max size magnet with stable quality
like the cylindrical magnet,
the max radial magnetize direction size is 100mm
the max axel magnetize direction size is 250mm
these are stable size, some factories produce almost 300mm but the quality is not stable.

2. Big size magnet separator is not made by one magnet
Someone misunderstands the magnet separator, thought that is made by one magnet. In fact, that is assembly by many small pcs magnet, and use stainless to cover it. In fact lots of magnets assembly are made from many small pcs magnets.

Big size neodymium magnets are strong

Large neodymium magnets are the practical magnets, that create a strong magnetic field and possess the best magnetic properties. They are known as strong because they resist the demagnetization and possess high saturation magnetization. It is actually the alloy of iron, boron, and neodymium forming the crystalline structure.

VARIATIONS BETWEEN THE PERMANENT MAGNETS AND THE ELECTROMAGNETS.

VARIATIONS BETWEEN THE PERMANENT MAGNETS AND THE ELECTROMAGNETS.

 

In every day of life and every sector, permanent magnets (likes Neodymium Magnet / Samarium Cobalt Magnets) or electromagnets are being used and it is important to be able to distinguish between the two magnets.

 

Background

 

There are various types of magnetic products, ranging from those we use at home, for offices to sizable industrial magnets that can easily lift and move whole automobiles or other hefty objects made of metal just through their magnetic intensities. Thus, magnetic functions are different in each scenario.

 

In lieu of this, the article will focus on both the permanent magnets and electromagnets

 

Generally, a magnet is a material or metallic object that produces a magnetic field; it produces a force that pulls on other ferromagnetic materials such as Iron and attracts or repels others. All crystals in the core of magnetic materials depend on producing a North pole and a South pole.

 

Different or opposite poles attract one another while like or same poles repel. That is, North and South pole attract, while North and North or South and South repel. Magnetic products are found and useful in various places such as residences, offices, industries and even in imaginative crafting. The importance of magnets cannot be over emphasized.

 

Magnetic Intensities

 

The magnetic fields (called B or B-fields) are produced  by the moving electric currents or charges. These flows are invisible streams to ordinary eyes in which charged fragments circulation.

A magnetic field is a vector field that describes the magnetic influence of electric charges in relative motion and magnetized materials. Magnetic fields are observed in a wide range of size scales, from subatomic particles to galaxies. In everyday life, the effects of magnetic fields are often seen in permanent magnets, which pull on magnetic materials (such as iron) and attract or repel other magnets. Magnetic fields surround and are created by magnetized material and by moving electric charges (electric currents) such as those used in electromagnets. Magnetic fields exert forces on nearby moving electrical charges and torques on nearby magnets. In addition, a magnetic field that varies with location exerts a force on magnetic materials. Both the strength and direction of a magnetic field vary with location. As such, it is an example of a vector field.

A charged particle moving with constant speed produces an electric field as well as a magnetic field. This means, when a charged particle moves with constant speed without acceleration, it generates an electric current and magnetic field.

 

Permanent Magnet.

 

A permanent magnet is obtain from carbon-rich materials and attracts ferromagnetic materials, ferrimagnets or ferrites. Ferromagnets are objects made from materials that are magnetized and create their own persistent magnetic field. They are materials attracted to a magnet and these include the elements iron, nickel, cobalt, some alloys of rare-earth metals and some naturally occurring minerals such as lodestone.

Permanent magnets are utilized day to day in various areas as stated earlier, example of this is loudspeakers, electric bells, refrigerator magnet used to hold notes on the refrigerator door, relays amongst others.

In the case of permanent magnets this field remains over time without weakening

 

How Permanent Magnets allured

 

Heating the object higher than its Curie temperature, allowing it to cool in a magnetic field and hammering it as it cools. This is the most effective method and is similar to the industrial processes used to create permanent magnets.

Placing the item in an external magnetic field will result in the item retaining some of the magnetism on removal. Vibration has been shown to increase the effect. Ferrous materials aligned with the Earth’s magnetic field that are subject to vibration (e.g., frame of a conveyor) have been shown to acquire significant residual magnetism. Likewise, striking a steel nail held by fingers in a N-S direction with a hammer will temporarily magnetize the nail.

 

Stroking: An existing magnet is moved from one end of the item to the other repeatedly in the same direction (single touch method) or two magnets are moved outwards from the center of a third (double touch method)

The permanent magnets can continue to be totally magnetic without external force such as heat energy, other tough magnetic fields or strong forces. If it is subjected to these effects it can be fully demagnetized.

 

What are electromagnets

 

An electromagnet is a soft metal coil made into a magnet by the passage of electric current through the coil surrounding it. The more the amount of current that flows with the coil the stronger the magnetic force of the electromagnet. In other words, an electromagnet is made from a coil of wire that acts as a magnet when an electric current passes through it but stops being a magnet when the current stops. Often, the coil is wrapped around a core of “soft” ferromagnetic material such as mild steel, which greatly enhances the magnetic field produced by the coil. The coil in electromagnet is referred to as solenoid.

 

If the coil of wire is wrapped around a material with no special magnetic properties (e.g., cardboard), it will tend to generate a very weak field. However, if it is wrapped around a soft ferromagnetic material, such as an iron nail, then the net field produced can result in a several hundred- to thousand fold increase of field strength.

 

Electromagnets are used in all kinds of electric devices, including hard disk drives, speakers, motors, and generators, as well as in scrap yards to pick up heavy scrap metal. They’re even used in MRI machines, which utilize magnets to take photos of human inner parts.

 

Electromagnets can be switched on and off and It can do this because it is an electromagnet. When current flows through a wire, a magnetic field is produced around the wire and an electromagnet is formed. The magnetic field can be turned off again by switching off the current. Around every magnet there is an invisible magnetic field. Magnetic field. Further, unlike permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. The poles of an electromagnet can even be reversed by reversing the flow of electricity. An electromagnet works because an electric current produces a magnetic field.

5 Basics Factors Of Neodymium Magnets

NdFeB is the most widely used magnetic material due to the highest specific energy density and low cost of production. This rare earth material is composed of the elements neodymium, iron and boron. Magnets of NdFeB are colloquially called neodymium magnets. They are very versatile because of their properties. NdFeB magnets are permanent magnets with a given direction of magnetization (anisotropic) and behave extremely stable against demagnetizing fields.

What Does Neodymium Magnets Use For:

  • Generators and electric motors
  • Magnet adhesive systems
  • Hall sensors (as encoder magnets)
  • filter systems

Limitations of Neodymium Magnets:

  • The operating temperature of magnets, depending on the grade, like the N grade, in most cases only 80 ° C. and the H grade, the maximum temperature is 230 ° C. But even you buy N grade, it does not mean the magnet must be supported the 80° C. If the thickness is thin, that will be lost magnetic in 75° C or lower.
  • Due to the high iron content of the neodymium magnets, these tend to corrosion. So it need coating material.
  • High sensitivity to impact or pressure load

Coatings of Neodymium Magnets:

The neodymium magnets are delivered with the following two coatings:

  • NiCuNi nickel coating (shiny metallic)
  • Zn Coating
  • Black/Grey epoxy coating

Usage notes of neodymium magnets:

Please read the warnings before using magnets. Neodymium magnets can be attached by gluing or snapping. If the neodymium magnet is attached to a magnetic object, you should make a previous test with a magnet between the magnet and the object, for example, fabric or polystyrene.

Neodymium magnets in different shapes and sizes

Neodymium magnets can be found in the form of discs, cuboids, cubes, rods, rings or balls and in different sizes. So you get the Neodymium magnets in cubic form, for example, in sizes between 1mm and 20mm. But lots of manufacturers do not like to produce the magnet smaller than 1mm, because that is hard to produce. Even the China magnet manufacturer. If you ask them, you would find that the 1mm magnet’s price is higher than the 2mm. And most of the time, they will increase the MOQ.

neodymium and ferrite magnets

What is the difference between neodymium and ferrite magnets?

The active study of magnetic materials began in the era of the development of electrical engineering when the relationship between the electric and magnetic fields was revealed. Now, no electrical product can do without them.

Nowadays, due to low cost, neodymium and ferrite magnets are most widely used. The first includes three main elements: iron, boron, and neodymium, which is indispensable in the aerospace and aviation industries, as an additive for the production of superalloys. In addition, the metal is widely used for the production of thermoelectric and special dielectric materials, fiber optic devices, as well as colored and painted glass for various purposes.

Both neodymium and ferrite magnet contains a large percentage of iron. In addition, the alloy may include several other elements, such as nickel, titanium, tungsten, chromium, cobalt, aluminum, barium, etc. Doping allows one to obtain the desired physical properties of the alloys.

Neodymium-based magnetic materials have a high value of residual induction and coercive force that keeps domains in an oriented state for a long time, even when exposed to external adverse factors. This is perhaps the main thing that distinguishes a neodymium magnet from the usual one.

The force of attraction of a conventional ferromagnet in ten years is reduced by more than half, while devices from neodymium lose no more than a couple of percents during the same time. Fantastic properties allow scientists and engineers to use materials from rare earth in the responsible nodes of electrical equipment, which requires the constancy of parameters over time. The durability of the alloy makes it possible to save not only on the cost of products but also on their maintenance.

What is the difference between neodymium magnets and ordinary ones? Due to the large residual induction, the neodymium alloy has a relatively large value of magnetization. The large force of attraction of products, with smaller sizes, mass, and relatively low cost, make this type of material preferable.

Neodymium magnet, the difference in characteristics of which compared to other brands of ferromagnets is so significant, can be found everywhere, both in everyday life and in production. The main areas of use: electrical and electronic products, fixing and technological parts, medical and special devices, household products, etc.

Most of the products presented on the website osenc.com are made of neodymium alloy.

China Magnet

Advantages Of Chinese Neodymium Magnets

So far, the greatest force of magnetic products is rare earth magnets. And their basis element is neodymium, in addition, boron and iron are present in the alloy. At the same time, almost all neodymium magnets are Chinese for sale. Lots of people want to ask why. The fact is that it is China is the main supplier of rare-earth elements (in particular, neodymium) on the world market.And there lots of neodymium magnet manufacturer in China. As a result, most of the products from these metals are produced in China.

Features and application
Chinese neodymium has a lot of advantages, the main ones are:
* Maximum magnetic energy;
* Maximum coercive force;
* Maximum residual magnetism;
* Preservation of working properties (for 10 years only 1% of magnetic energy is lost);
* High corrosion resistance;
* The ability to manufacture products of any shape (discs, rings, segments, bars, etc.).

Lots of neodymium magnets from China is normal shape, like Cylindrical,Square, Disc. But as we know in the industry world, in the production we need the custom magnet.  They are very different. Different shape, different magnetic direction and different coating.

But no matter what different it is, they are used in:
* Clamps and clamps (from household tool holders to magnetic clamps of heavy equipment);
* Systems of cleaning, separation, and filtration;
* Metal detectors;
* Hard disk drives and erasing heads;
* Acoustic equipment;
* Turbines and generators;
* Compression, lifting, stepping, and electric motors;
* Medical equipment.
In addition, neodymium is used to produce all sorts of toys and sets for tricks. In everyday life, they are also often used for many different purposes.

Designation and classification
All neodymium magnets – from China, they, or from Russia, it does not matter – they must have an alphanumeric designation describing the main performance characteristics of the product. The letter thus denotes the temperature range in which the magnet retains its properties, the figure – the so-called magnetic energy or the “pull force”.
According to working temperatures, neodymium is divided into the following classes:
* N – up to 80 ° C;
* M – up to 100 ° С;
* H – up to 120 ° C;
* SH – up to 150 ° C;
* UH – up to 180 ° C;
* EH – up to 200 ° C.
Temperatures below zero do not affect the working properties of the neodymium.
When choosing a neodymium magnet from China, one should remember that the separation force depends not only on the physical characteristics but also on the dimensions of the product (more precisely, the area of the contacting surface). For example, a 25×20 magnet comes off easier than a 40×5 magnet, since it has a smaller area of contact with metal. However, due to the longer magnetic lines, its grip strength will be higher.

How Sintered Neodymium Magnets are Made

Exactly How Neodymium Magnets are Made

Exactly How Sintered Neodymium Magnets are Made
We talked about the steps associated with producing neodymium magnets, with some notes on what this suggests for real magnet customers.

1. Main Materials
The standard compound for the majority of Neodymium magnets is Nd2Fe14B. But in the real production, the chain reaction can be much more complex. Here is the generally made use of reaction :

57 Fe + 8 B + 10 Fe2O3 + 7.5 Nd2O3 + 52.5 Ca -> Nd15Fe77B8 + 52.5 CaO

Vacuum Cleaner Induction Heating System

What we need to pay attention is higher temperature level magnet grades, extra| components are included. When small percentages of Iron (Fe) are changed with Cobalt (Co), the power of magnet will enhance at raised temperature levels, however the intrinsic coercivity will be lowers. If tiny parts of Neodymium (Nd) are changed with Dysprosium (Dy), the intrinsic coercivity is enhanced, however the maximum power item (BHmax, an excellent step of a magnet’s power ) lowers. In normal, the magnet producer use both Co and Dy together. So the power and performance will be great.

2. Melting
In order to protect the product. In the production, the material need happens in a vacuum cleaner induction heating system. The system is heated up by electric swirl currents via it, the vacuum cleaner can make the pollutants out of the production.

3. Milling

In order to make the material to typical 3mm,magnet supplier will use the jet milling transforms the rhas magnetizationial right into a powder with a really tiny dimension.

4. Pressing

Pressing Actions
The powder need to be pressed together to create a shape that has magnetization orientation. In the production, referred to as die-upsetting, the powder is pressed with a die right into a solid body at raised temperature levels of concerning 725 ° C. The solid is after that positioned in a 2nd die, where it is pressed to a larger form that has to do with fifty percent it’s initial elevation. This straightens the favored direction of magnetization alongside the pressing orientation. For some forms, there are approaches that consist of a component that creates an electromagnetic field throughout pushing to align the particles.

5. Sintering
Sintering is a usual procedure in powder metallurgy. The main material is pressed at raised temperature levels (as high as 1080 ° C) below the material’s melting factor, till its particles comply with each various other.

6. Machining
The sintered magnets are reduced to the customer wanted form making use of a grinding procedure. Much less generally, complicated forms are made with electrical discharge machining (EDM). As a result of the high material price, material losses because of machining are maintained to a minimum. No reliable ways of reusing the waste have actually been created.

7. Coating
The specific magnets are electro coat with 3 material: nickel & copper & nickel. This is essential due to the fact that un-coated neodymium magnets are very easy to “rust”, and also will promptly miss their magnetic power in the daily witness.

8. Magnetization
Now, the magnets have a specific orientation
of magnetization, however, they are not magnetized. They are put in a mold(we also called it fixture) that will certainly show the magnet to an extremely electromagnetic field for a short moment. It’s generally a huge coil of cable around the magnet( s). The magnetizing devices make use of banks of capacitors as well as a truly massive voltage to obtain such big current for a split second.

9. Inspection
About the quality of the resulting magnets is the inspection. For a range of properties.
p measuring projector confirms the measurements. The thickness of the coating, in order to check it, will use x-ray fluorescence modern technology to check.

What all this suggests for customers of neodymium magnets

A magnet with the nickel plating scratched away, exposing the raw NdFeB magnet below
Neodymium magnets are created by powder metallurgical techniques. Their feature very closely looks like a ceramic, instead of a metal. They are not conveniently machined, so we do not suggest attempting to make them.
Neodymium magnets are extremely difficult and breakable. Regardless of the metal look of their nickel coating, they are not as strong as steel. If based on sharp effects, such as enabling them to knock right into each other, they can quickly break or damage. Treatment, as well as correct handling, are necessary}.
We do not suggest press-fitting neodymium magnets. Magnets are frequently glued into a pocket that is a little bigger than the magnet, instead of press-fitting.
We do not suggest making use of a threaded magnet. While it’s possible to reduce strings, they do not stand up well under torque.

Special shape magnet

How does the magnet die?

The magnet can be dead? How ridiculous it is! It just a good, not animal, not human being. In fact, the magnet can be dead. But what we mean is that it lost the power, in another word, is lose its magnetism. Demagnetization and degaussing is how they die.

The first reason: Heat

Yes, the temperature is a very important factor. Most of the magnet die in their hand. If you heat the magnet and reach a certain temperature, the magnet loses its magnetism. Different magnets have different temperatures. For example, the temperature of N series NdFeB is 80 degrees. As soon as this temperature is reached, the magnet begins to lose its magnetism. And this temperature, we call it the Curie temperature. Losing magnetism does not disappear in a flash. It is slowly. The higher the temperature, the faster the time of death. At the same time, the volume is also a factor. At the same high temperature, if the volume of the magnet is larger, the time of death will be longer. On the contrary, if the volume is small, then it will die in just a second. Therefore, in the process of using the magnet, it is necessary to pay attention to the working environment temperature.

The second reason: Magnetic field

Coercive Force, A very strange noun, many guests do not understand what this means. It is also difficult to explain in technical terms. In the simplest terms, magnets with high coercivity such as Sm-Co and Nd-Fe-B, and magnets with low coercivity such as Alnico ferrite magnets cannot be placed. together. In particular, the difference in coercivity is particularly large, because magnets such as Sm-Co and NdFeB kill magnets with small coercivity.

The third reason: Crush

Old magnet, like Alnico,will be easy lost its lift. Just because of the shock or hit with a hammer. But the modern magnet do not happen this problem.

No matter you buy magnet or sell magnet, we also need to know how to stock the magnet. Because if the magnet lose its power , its useless. It is not easy to resend it to the factory and magnetizing again.

Custom Permanent Neodymium Magnet

Interesting Things You Can Do With Custom Rare Earth Magnets

The Neodymium or rare earth magnet is certainly the best when it comes to strength and performance. The rare earth magnet features pull-force of 10 times stronger than other types of magnets and approximately 20,000 times better than the magnetic field generated by our planet. Before you plan to buy custom neodymium magnets, you must know that these magnets are also brittle. However, it can withstand much greater stress than ferrite magnets.

Now you might be wondering what the uses of neodymium magnets are. Due to affordable cost and bulk availability, the neodymium magnets are used in a variety of projects. You can also use them for creating some DIY products, which would be the following.

Magnetic sculpture:

You might have seen a variety of videos online in which the artists use custom made magnet is used to produce several different sculptures. You can also get creative and use custom magnet shapes to turn your fantasy structure a reality. You do not need to use all the magnets because you can use other metal objects to create an artistic sculpture. You just need to search for the DIY projects with custom neodymium and there will be plenty of things to do with this magnet.

Tool holder:

Neodymium magnets can be available in several different shapes. You do not need to buy all of them because you just need ½” diameter cylindrical neodymium magnet. It is not about building a tool holder for your garage, but for carrying with you. Suppose you are a mechanic and want to carry some essential tools to the job site, you should keep a small but strong neodymium magnet in your pocket. It can easily hold ratchets, wrenches, and other tools when you are working on a project. You can also use a tiny neodymium to hold your keys safely in your pocket.

Produce a mini magnetic field:

Yes, it is possible to create mini magnetic field by using custom made magnets. You need a round neodymium magnet and a copper piping of the same diameter as the round shaped neodymium. Now you have to hold the copper tube vertically and drop the round neodymium magnet in that tube. You might think that it will drop down like a ball bearing but that is not going to happen. The magnet creates a mini magnetic field as it passes through copper and therefore it does not drop like a ball bearing. Try this experiment and then repeat it in front of your friends.

Floating paper clip:

It is a classic experiment often performed with the neodymium magnet. Get a small neodymium and stick above the floating paper clip stand. Now tie the paper click with a nylon thread and tie it just 2” below the magnet. The bottom of the stand will keep the nylon thread in its place and the paper clip will appear like floating in air. It can be a great decorative sculpture. You can use a large strong magnet and replace paper clip with any other metal object to make this experiment look more appealing.

There are many other DIY things you can try with custom magnets. The above explained experiments are simple and quite fascinating and therefore you must try them.
