At present, the NdFeB magnet on the market in the production process is not magnetic, there is no magnet of mutual exclusion and mutual attraction, NdFeB magnet only after the process of magnetization can have magnetic, then how to the NdFeB magnet magnetization treatment.
There are many ways to magnetize NdFeB magnets. At present, there are two commonly used methods to magnetize them. Method one: DC magnetization, Method two: pulse current magnetization, these two methods are currently the mainstream magnetization methods on the market.
1, DC magnetization method: DC magnetization method in the right
The electromagnet magnet is used in the process of magnetization of NdFeB magnet. Its structure is shown as follows: When the electromagnet magnetizer is magnetized, the coil will give direct current, and then the size of the gap between the two iron cores can be operated by adjusting the nut. Before charging the NdFeB magnet, we first need to treat the surface of the magnet with water. Then we need to put the NdFeB magnet into the core gap of the magnetizer to clamp, and then through the direct current to reach the maximum charge time of 3-4 seconds, you can cut off the power, and the magnet has been magnetized.
2, pulse current magnetization:
Pulse current magnetization, when the NdFeB magnet is magnetized, the pulse current magnetization device is needed. Its main composition is the pulse device and the magnetization coil. Its magnetization field strength is very high.
