NdFeB permanent magnet is mainly used in Micro-motor, Electronic Industry, Car Industry, Petrochemical, NMR devices, Sound equipments, Maglev System, Magnetic drive and Magnetotherapy system, and its also used in Motorbikes, Car oil-duct's magnetization, with the aim of saving oil.
Earth permanent magnet (NdFeB) has the strongest magnetism nowadays. It does not only has high remanence, high coercivity, high energy product, and high-functional, but also it can processed into a variety of sizes easily. Now, it is widely used in avigation, spaceflight, electron, electrical sound, electrical machinery, apparatus, meters, medical technology, and especially apply to develop high-performance, small and light replacements.
