The Sintered NdFeB magnet is known as one of the strongest magnet
materials, with high remanence(Br), high coercive force(Hcb) and
high energy product(BH), it is easily formed into various shapes,
sizes and widely used in many fields such as speakers, motors,
sensors, alarms, and many other electrical and electronic
facilities.
