Currently on the market in the production process of powerful magnets are not magnetic, there is no mutual repulsion of magnets attract each other's properties, powerful magnets only after the process of magnetization to have magnetic, then how to magnetize powerful magnets for processing.
The magnetization method of powerful magnets, the more commonly used methods have two reports on its magnetization process, method 1: DC magnetization, method 2: pulse current magnetization, these two ways are currently the market more mainstream magnetization methods.
Method 1: DC magnetization method in the process of magnetization of powerful magnets need to use to electromagnet magnetizer, its structure is shown in the figure below, to the electromagnet magnetizer in the magnetization of the coil will be given into the DC current, and then in the size of the gap between the two cores can be adjusted through the operation of the nut, in the powerful magnets to charge the magnet between the first thing we need to be the surface of the magnet to be processed with water, and then we need to Powerful magnets into the magnetizer core gap clamping, and then pass into the DC power to reach the maximum value of the charging time of 3-4 seconds after the power can be cut off, the magnet magnet has been magnetized.
Method 2: pulse current magnetization, in the magnetization of powerful magnets need pulse current magnetizing device, his main composition is the pulse device and magnetizing coil composition, its magnetizing field is very high, in the work of a very strong impulse current through the magnetizing coil, in the instant a strong magnetic field so that the magnet in the magnetizing coil of the magnetic stack magnetization.
