What is the application scope of the ferrite of permanent magnets?

　　Ferrite of permanent magnets is mainly used for low-speed torque motor, starting the motor, sensor, magnetic thrust bearing and other magnetic systems.

　　Permanent magnetic material of Neodymium magnets is the third generation of rare earth permanent magnetic materials, the magnetic remanence, coercive force and maximum energy product are all higher than the former, non-friable, has better mechanical properties, alloy with low density, is conducive to the magnetic component of the light, thin, small and mini scale. But the magnetic temperature coefficient is high, limiting its application.
