We can't see the magnetization method of magnet products with the naked eye. We don't know whether it is ordinary magnetization or multipole magnetization. We can only check it by using the magnetic pole observation piece, and judge the magnetization method and the number of magnetization poles of magnet products through the magnetic pole observation piece.
The magnetic pole observation piece is also called the magnetic pole display piece, the magnetic pole detection piece, and the magnetic graphics card. Different people call it different.
The main function of the magnetic pole test piece: Using the magnetic pole observation sheet, you can see the number of magnetizing poles, magnetizing method, strong magnetic surface and weak magnetic surface of the magnet.
Identification method of the magnetic pole observation sheet: test the magnetization stage of the magnet: place the magnet product in the developing area of the magnetic test piece, you can clearly see the magnetization stage of the magnet product, and the magnetization stage of the magnet product is an even number, because It's all one-to-one.
Identify the magnetization method of the magnet: the magnetization methods of magnet products are commonly axial magnetization, radial magnetization, and axial magnetization products can be seen on the height surface of the magnet, which divides the height (ie thickness) of the magnet into two halves. The demarcation line presents a cross shape, while the radial magnetization does not. The radial magnetization products are evenly divided into several parts, one vertical and one vertical.
Identification of strong magnetic surface and weak magnetic surface: multi-stage magnetization products, the magnetic force of one magnetic force surface is stronger or weaker than the other magnetic force surface, in the development area of the magnetic pole test piece, it can be distinguished according to the clarity of the magnetic force decomposition line, the magnetic force line is clear One side is the strong magnetic surface, and the slightly blurred side is the weak magnetic surface.
The above is an introduction to the use and functions of the magnetic pole observation sheet, originally edited by Chinese magnet manufacturerCourage Magnet.
