1. N pole, S pole charge and reverse
This situation often occurs with some special magnets, such as rectangular magnets with beveled corners. Some customers require that the surface with the corner cut in the upper left corner be the S pole. The probability of magnetization errors for such magnets will be much greater.
2. Wrong magnetization method (direction)
This may be due to poor communication with the customer. For example, Xiao Fu had a colleague charge a D3.5*20 cylindrical magnet with radial magnetization. The customer originally requested axial magnetization. This kind of It's also quite special, but because I haven't confirmed it yet, I just made my own decision, which resulted in magnetization errors. There are also square magnets that have this kind of magnetization error, whether they are thickness magnetization or side magnetization. The tile-type magnets on the motor that require matching magnetization are not matched for magnetization, etc. 3. Magnetization is not saturated
This situation is relatively rare, but there will be cases. For example, a magnetizing fixture cylinder can only be charged with 20 circular magnets at a time. If more than 20 pieces of circular magnets are charged, the magnets on it may become unsaturated. Of course, there are also the magnetizing machines. The problem.
4. The magnet has uneven magnetic properties
The magnet may be affected by uneven magnetic field distribution during the magnetization process, resulting in uneven magnetism. This will cause the magnet to produce an uneven magnetic field when used, affecting its performance and effect.
