Magnets Are A Very Common Thing in Life

Magnets are a very common thing in life. After NdFeB magnets are placed for a period of time, white or other colored spots will appear on the surface, which will gradually develop into rust spots. Under normal circumstances, NdFeB magnets will appear rust spots. What are the reasons for analysis?

1. The dirt on the surface of the magnet before electroplating is not well cleaned;

2. Magnet oxidation caused by damage to the packaging seal of the magnet;

3. The magnet should be stored in a place with humidity, poor air circulation and temperature difference;

4. The electroplating time is not enough or the process flow problem;
