Magnetization magnetizes the magnetic substance or increases the magnetic properties of the magnet with insufficient magnetic properties. Generally, a magnetic object to be magnetized is placed in a magnetic field formed by a coil through which direct current is passed. The magnetization direction can be divided into thickness magnetization, radial magnetization, and the like. [Magnetizing machine] 1. Constant current magnetizing machine working principle: The constant current DC current is passed through the coil to make the coil generate a constant magnetic field. Suitable for magnetization of low coercivity permanent magnet materials. Second, the working principle of the pulse magnetizer: through the instantaneous pulse of large current in the coil, the coil produces a short super strong magnetic field. Suitable for high coercivity permanent magnet materials or complex multi-pole magnetization. It is widely used in the production and application of permanent magnet materials. It is suitable for the magnetization of various permanent magnet material parts and components, such as: aluminum nickel cobalt series, ferrite series, rare earth permanent magnet series, etc., with high efficiency and reliability. The equipment has no special requirements for the power supply configuration of the work site, and it is convenient and flexible to use.
