Ring Magnet, Rare earth magnet, strong magnet, Sintered NdFeB magnet, Used for Speaker, Sensor, motors, holding magnet, etc.
Neodymium magnets (Nd-Fe-B) are composed of neodymium, iron, boron and a few transition metals. These magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as rings, blocks and discs. Their max energy product can be 35MGOe~50MGOe , Neodymium magnets are developed rapidly and applied widely due to their perfect characteristic, rich raw material resource and reasonable price.

★ Application of big ring magnet
The ring neodymium magnet is a kind of energy material, which can produce the stable magnetic field in the certain space. Because of its highest coercive force and , especially under the 20℃～150℃, it works better than any other kinds of permanent magnets. So it is widely used in many areas, especially in the high-tech area. Basing on its physical principle, the usual applications are as below:
Electric energy to mechanical energy: as electromotor,speaker,VCM (Voice Coil Motor);
Mechanical energy to electric energy: like the generators, telephone receiver, and measuring instrument;
Mechanical energy to Mechanical energy: as the magnetic separator, magnetic suspension, magnetic actuators and magnet chucks;
Magnetic field’s physical effect: like the Nuclear magnetic resonance, magnetic cleaning device and magnetic oil-saving mechanism.
