A permanent magnet is just a magnetic material before it is magnetized. In order to provide a magnetic force to a permanent magnet, a magnetic field of a fixed strength is established and made to reach the desired saturation continuous magnetic flux density of the permanent magnet.

----The magnetizing power supply is such a special equipment, which can magnetize the permanent magnet to meet the professional requirements such as the number of poles, the shape of the magnetic pole, and the magnetization intensity. It has been widely used in AlNiCo, ferrite, rare earth ( Magnetization of permanent magnet materials such as samarium cobalt, neodymium boron).

----Generally speaking, a magnetizer consists of a high-power power supply for generating a high-intensity magnetic field and a magnetizing coil or fixture. Users need to choose different types of magnetizing power supplies and magnetizing fixtures or coils according to the different magnetic materials and the required number, shape, size and other parameters of the magnetic poles.
