Wholesale neo magnet neodymium magnet n52 ring shaped magnets
Neodymium ring magnet is also known as tube magnet, a round disc magnet with a straight hole along the centre, the hole in centre ensures great versatility. Most ring magnet is with north and south poles on the flat circular surfaces (this is called as axial magnetisation). The few exception that is diametrically magnetised is specifically marked. Also, Multi pole ring magnet, even radially magnetized ring magnet, is more and more referred in this industry now. NdFeB magnet is one of the most common used magnet in the world today. The products are widely used in the electronic products like disc, mobile, earphone, speaker and other products.

Advantages:
1. High Performance :
Having good resistant to demagnetization.
2. High Consistancy :
The Cpk of Remanence (Br) and Intrinsic Coercive Force (Hcj) are much higher than 1.67. The consistency of the surface magnetic field and magnetic flux can be controlled at +/-1%.
3.High Working Temperature :
The neodymium magnet of BEARHEART can satisfy the working temperature requirements with excellent temperature resistance. The AH series with 40 kOe super-high coercive force can replace Smco magnets in most Applications.
4.High Anti-Corrosion:
The perfect coating of BEARHEART Magnets can meet many anti-corrosion requirements. The salt spray test and humidity heat test of the high anti-corrosion coating Nickel+Copper+Epoxy is typically more than 1000 hours.
Applications
Strong Ring magnet is being designed into a new generation of motors, generators, hydraulic cylinders, pumps & sensors, rotor shafts and more. What's more, it remain very popular in high end loud speakers and high intensity separators.

FAQ:
Q1. What is the difference between a neodymium magnet and a regular magnet?
A1. The key difference between Neodymium magnet and Regular Magnet is that the neodymium magnet contains neodymium, iron, and boron as the key chemical elements whereas the regular magnet contains iron as the key chemical element. Neodymium magnet is a form of strong magnet made from rare earth elements such as neodymium.
Q2. Is it safe to touch neodymium magnets?
A2. Neodymium magnets can jump together, pinch the skin and cause serious injuries. Neodymium magnets will leap and slam together from several inches to several feet apart. If you have a finger in the way, it can get severely pinched or even broken.
Q3. What can neodymium magnet destroy?
A3. Strong magnetic fields of neodymium magnets can damage certain magnetic media such as credit cards, magnetic I.D. cards, and legacy media such as cassette tapes, and videotapes. They can also cause damage to TVs and computer monitors.
Q4. What are rare earth neodymium magnets?
A4. Rare earth neodymium magnets are strong magnets made of neodymium, iron, and boron. They are the strongest type of permanent magnets available and have a variety of applications.
Q5. What are the benefits of using rare earth neodymium magnets?
A5. Rare earth neodymium magnets are known for their strength, durability, and versatility. They have a very strong magnetic pull, making them ideal for holding applications, and their small size and shape make them easy to use in a variety of settings.
