What is a good magnet supplier?
We guess it should be ” Help you get what you want”.
But, how? We guess it should be 3 points.
- help you make sure the magnet you want is you really need.
- Produce it, and make sure it meets your requirements.
- Make sure you get them in time.
If make 3 points in 1 sentence, that is it should offer magnet and customer service.

Rare earth magnets are the strongest type of the permanent magnets manufactured and are integral to the high tech industry, especially in the clean energies, like the wind turbine generators and the electric vehicle motors. China extracts and it produces over 95% of the world’s rare earth minerals, moreover has cut its exports since the year 2010. In addition to the supply chain concerns, extraction process is extremely destroying the environment.
But which magnet is stronger than the neodymium magnet?
Recently, a lot of experimental work has been done on the Iron and Nitrogen in order to combine for manufacturing a much stronger iron nitride magnet. In the beginning, experiments produced only thin films or powders which were not appropriate and suitable for many applications. But, when the fabrication process was employed and it produced the magnet in the bulk form that can be used in a number of applications. Moreover fabrication process in very compatible with the existing mass-production techniques. Nitrogen and the iron inputs are comparatively low cost, hence enabling extremely cheap permanent magnets which exceed performance of the rare earth magnets.
Osenc offer customer big neodymium magnet
Benefits and features of the iron nitride
- Iron nitride permanent magnet does not need any rare earth inputs. It uses low cost and common nitrogen and the iron inputs.
- Iron nitride permanent magnets are environment friendly.
- Iron nitride permanent magnets are compatible with the mass production techniques.
- This strongest iron nitride permanent magnet is used in many high tech applications that include electronics, wind turbines and electric motors.
- The theoretical limit of the magnetic properties if iron nitride permanent magnet are more than the twice, maximum reported magnetic energy of the rare earth magnet.Osenc Made Such Big Size Magnet
The other two magnets which are considered stronger equally as neodymium magnets
- Dysprosium has highest magnetic field strength than all other elements and it is added to the neodymium magnets for increasing their resistance towards corrosion and demagnetization. The neodymium magnets are quite prone to corrosion and as they are very hard, dysprosium makes them brittle.
- The other stronger magnet is the Somarium Cobalt. As compared to the neodymium, SmCo provides you with the unique capabilities like higher energy density at the elevated temperatures. Somarium cobalt is now equally in line with neodymium magnets in terms of their usage in applications.
We have many devices currently that are in use today which employ use of the magnets. Headphones, earphones and speakers have the magnetic coils and magnets that convert the electrical signals into sound. Propellers and the fans also have magnets which converts the electrical energy into the mechanical energy and the vice versa. The power plant generators use magnets to drive the generators. Strip magnets are used by the freezers and the refrigerators as door seals to seal the inner atmosphere of the freezer and the refrigerator. Now, Somarium Cobalt and the Dysprosium are being used in many of the applications in place of the neodymium magnets.
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.
Want such a big magnet? contact us , Osenc can help you
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.

A neodymium magnet is also called as NIB, Neo magnet or NdFeB Magnet. It is the permanent magnet which is made from the alloy of neodymium, boron and iron to form the crystalline tetragonal Nd2Fe14B and is most widely used kind of rare earth magnet. In 1982, it was developed independently by the Sumitomo Special Metals and General Motors. Strongest type of the permanent magnets that are commercially available are the neodymium magnets.
Due to the different manufacturing processes, neodymium magnets are divided into the two sub-categories:
- Bonded NdFeB magnets
- Sintered NdFeB magnets
In modern products they have replaced other magnets in many of the applications which require permanent strong magnets like motors in the cordless tools, magnetic fasteners and hard disk drives.

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.
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.
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.
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.
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.
Osenc committed to developing, manufacturing, selling and serving of high quality customized neodymium magnet with competitive price at fastest time.
