Currently, most of the motor manufacturers use strong neodymium permanent magnets in their motors. For example, there is one of motor, called linear motor, using open magnetic field instead of closed magnetic field, generating moving magnetic fields by powerful ndfeb rare earth magnets, can transform electric energy to linear motion mechanical energy directly without any intermediate conversion mechanism of transmission.

In recent years, their applications expand day by day, and maglev train is one of perfect linear motor driving. The strong permanent block magnets are assembled on the steel rail. They are composed of magnetic track which is a very important part of linear motors.
