Advantage:
1. Neodymium magnet is regarded as “Magnet King” due to its recorded high remanence, coercive force and maximum energy product.
2. With Neodymium magnet rapid development, many high-tech products were developed. Especially its application in motors makes products miniaturization and micromation.
3. At the same time, because of its high remanence, coercive force and maximum energy product, this type magnet is widely used in servo motor, flat brushless motor, step motor, IT products, Nuclear Magnetic Resonance, speaker and other products.
