Magnet Disc is the most permanent magnet in the contemporary. Due to it have good remanence, coercivity and high performance, sintered NdFeB magnet have best magnetic, can support about 640 times of its weight. Now it have been widely used in electronics, electrical, mechanical, medical equipment and others.
