Large NdFeB Industrial Magnet Ring
NdFeB, the strongest type of permanent magnet with high remanence, high coercive force, high performance, is the most widely used among rare earth magnets. Gradually NdFeB magnets are replacing other types of magnets in modern applications. They can be processed into various size and widely used in many fields such as Sonic Equipment(Loudspeaker, earphone, microphone), Micro Special Motor(Voice Coil Motor, Step Motor, Servo Motor, Geared Down Motor, Synchronizing Motor), Medical Instruments(Magnetic Therapy Device, Water Magnetizer, Magnetic Resonance Image Device), Industrial Drives(Generator, Magnetic Crane, Magnetic Filter, Magnetic Clamp).
Here are many grades of neodymium magnets that can be chosen. Higher values indicate stronger magnets and range from N35 up to N52. Letters following the grade indicate maximum operating temperatures, which range from M(up to 100℃) to EH(up to 200℃).
