The magnetic pole observation plate can quickly detect the number of magnetized poles of the magnet

Identification method for magnetic pole observation film: Test the magnetization level of the magnet: Place the magnet product in the developing area of the magnetic film to clearly see the magnetization level of the magnet product. The magnetization levels of the magnet product are all even, as they are one-on-one.

The magnetization method for identifying magnets: The magnetization methods for magnet products are commonly axial magnetization and radial magnetization. Axial magnetization products can be seen on the height plane of the magnet, which divides the height (i.e. thickness) of the magnet into two halves, showing a cross shaped boundary. Radial magnetization does not exist, while radial magnetization products are evenly divided into several parts, one vertical and the other vertical.

Identification of strong and weak magnetic surfaces: For multi-stage magnetized products, the magnetic force of one magnetic surface is stronger or weaker compared to the other magnetic surface. In the developing area of the magnetic pole test piece, the clarity of the magnetic decomposition line can be distinguished. The side with clear magnetic force lines is the strong magnetic surface, and the slightly blurred side is the weak magnetic surface.
