Everyone knows that powerful magnets are very magnetic, especially large powerful magnets, which can easily hurt people when they are used. So how can strong magnets eliminate magnetism?
The method is very simple. The temperature resistance of the strong magnet is below 80 degrees. We only need to put the strong magnet on the fire for a few minutes. After cooling, you will put it next to the iron block and find that it has lost its magnetism and can no longer attract. Can't get up. The reason is that the strong magnet is magnetic because the iron atoms in the strong magnet are arranged regularly. After it is heated, the original arrangement of the iron atoms is disordered, and therefore it loses its original magnetism. Similarly, we can also use other methods to demagnetize the powerful magnet.
