Ring Magnet

Ring magnet is the hot sales magnet in the market. People can buy many different shapes, sizes, and magnetic materials (like neodymium, ferrite, samarium) from the store. As a neodymium magnet factory, we offer N, H, M, SH grade ring neodymium magnets with different coatings.

Different Hole

Ring magnets, no need to explain that, it has a circular shape and a hollow center.
About the hollow center, there 2 shapes in the market:

neodymium-ring-magnet

1.Normal Hole

The normal hole ring magnet can use for many different applications and their size can be bigger, like OD 250mm and ID 200mm. Most normal hole small ring magnets are used for headphones, and big ring magnets use for speakers.

2.Countersunk

countersunk magnet, most of them the hole is small. because the countersunk will fill in with a screw. And most countersunk neodymium magnets are used for fishing magnets. The biggest fishing magnet can hold almost 1-ton goods.

Powerful Ring Magnet

If you want to buy a powerful neodymium magnet, there are two options, first option is to increase the size of the ring, the second option is to use high-performance materials.
If you want to get higher power, like 1.6T (16000Guass), you should use the Halbach array.  The following Halbach array is we produced for MPG (Max-PlanckGesellschaft).

1.6T Halbach Array

The most popular ring magnet is the neodymium ring. They can bring supreme strength to the application because they are made of rare earth neodymium magnetic material. Most of the time, neodymium ring magnets are used in applications such as stereo systems, loudspeakers, motors, and sensors used in automotive and other high-tech, high-value applications, and in technology such as generators. Ring magnets are also utilized in new tech developments, such as robotics and hot new consumer electronics.

MRI

Used for applications

And one thing should be reminded. Most people believe the MRI (Magnetic Resonance Imaging) machine is made of a very big ring magnet. Because the name has “magnetic” and the machine has a very big hole. In fact, the MRI machine has some magnets inside, and all of them are small pieces, not too big.

Science Experiment
Lots of ring neodymium magnets are used in science. from engineering new applications to performing experiments and demonstrations. They are often used in simple demonstrations for students to illustrate magnetic force, such as showing how two magnets will either attract to each other or repel away.

Osenc offers powerful neodymium rings. Whether you are installing ring magnets into a high technology application or testing something, or make an experiment for the young scientists. we can offer you an excellent ring magnet to suit your needs. Contact us now to get more information.
