Neodymium magnet, also named NdFeB magnet, Neo magnet & Nd magnet, is mainly made of Neodymium, Iron and Boron with strongest power among all magnetic materials. Neodymium magnet can be easily shaped with high precision, widely used to motors, rotors, wind turbines, wind generators, sensors, loudspeakers, cars, mobile phones, home appliances, medical equipment, filters, and so on.

Organic Epoxy,Ni+Epoxy,Parylene Coating
Temporary Surface Passivation
Electric motors and generators use permanent magnets. Motors use electrical energy and convert it into mechanical energy. This energy is then used for various applications from pumping water to drilling.
Generators do the opposite. They convert mechanical energy into electrical energy. The best examples are the simple dynamo used in bicycles for illuminating a lamp, and the huge generators used in hydropower plants.
Strong Neodymium Sector Magnets for Passive magnetic bearings (PMB) achieve contact-free levitation of an object by permanent magnetic attractive or repulsive forces. Depending on the configuration, stabilization in radial, axial and tilt direction are possible. It is, however, not possible, to stabilized all degrees of freedom of a body by passive magnetic levitation, alone. This has been shown by Braunbeck who interpreted the prior findings of Earnshaw on the stability conditions in force fields for magnetic levitation. Diamagnetic materials such as superconductors are explicitly not considered in this statement. A very simple PMB design consists of permanent magnetic rings on the rotating shaft and the stator which stabilize the radial degree of freedom by repulsive forces.
