Neodymium Magnet, Sintered NdFeB magnet, the third generation of rare-earth permanent magnet, is the most powerful and advanced commercialized permanent magnet up to date. Neodymium Magnet has high coercive force, high energy and high performance/ cost ratio. It can be formed into various sizes and widely used in many fields such as aviation, electronics, instruments, meters, machines and medical instrument.
