NdFeB magnets have the high remanence , high coercive force, high energy product and high performance,cost ratio, also have the high temperature model to suit for high temperature condition. It is easily formed into various sizes, including tile magnet, magnetic cylinder, magnet block, sphere magnets, horseshoe magnets, can be single magnetization, two poles and multi-poles magnetization, are widely used in mini-motors, wind generators, meters, sensors, sound device.
