Magnetizer is a tool for magnetizing magnetic materials or magnetic components. Through it, we can apply a magnetic field to the permanent magnet products that need to be magnetized.
The basic principle of magnetization is to place the magnetizable object to be magnetized in a magnetic field formed by a coil with direct current passing through it. There are two ways: direct current magnetization and pulse magnetization.
If the magnetization field does not reach the technical saturation field, the remanent magnetization Bj and coercivity Hcj of the permanent magnet will not reach their proper values. So how to determine the energy of the magnetizer?
Firstly, the size of the magnetizing tooling is determined according to the size of the magnetized product and the magnetizing direction. Then calculate the size of the magnetic field in the center of the tooling. The size of the magnetic field of the tooling should be 3-5 times the coercivity of the magnet. Then the magnetization current is calculated. Based on the current and the voltage of the magnetizer, the capacity of the magnetizer’s energy storage capacitor is finally determined. Finally, the energy of the magnetizer is determined.
