We have been trading in the magnet industry for many years. A small number of customers indicated that the magnetic force of the permanent magnets they purchased was attenuated, and they usually suspected that it was the quality of the product itself. In fact, the quality of our products can stand the test of the market.Today let's take a look at what factors lead to demagnetization of permanent magnets:

1. Mechanical vibration and impact cause demagnetization.

2. High temperature demagnetization, the increase in use temperature will cause the magnet to demagnetize.

3. The change of the external current magnetic field causes demagnetization.

4. External magnetic field interference causes demagnetization.
