Everyone knows that strong magnets are very magnetic, especially large powerful magnets, which can easily hurt people when used. So how can a strong magnet eliminate magnetism?

The method is very simple. The temperature resistance of the powerful magnet is below 80 degrees. We just need to place the powerful magnet on the fire and bake for a few minutes. After cooling, you place it next to the iron block and find that it has lost magnetism and will no longer suck. Can't get up. The reason is that the strong magnets are magnetic because the iron atoms in the strong magnets are regularly arranged. After it was heated, the original arrangement of the iron atoms was disordered, so it lost its original magnetism. We can also use other methods to demagnetize powerful magnets.

Precautions for storing strong magnets:

1. Do not place strong magnets close to electronic equipment. If they are close, they will affect electronic equipment and control circuits and affect their use.

2. Do not store the magnet in a humid environment to avoid its oxidation, which will cause changes in appearance, physical characteristics and magnetic properties.

3. People with sensitive reactions to metal objects will feel rough and reddened if they approach the magnet. If the above reaction occurs, do not touch the powerful magnet.

4. Do not place magnets near floppy disks, hard drives, credit cards, tapes, debit cards, TV picture tubes, etc. If you place the magnet close to a magnetic recorder or other device, it will affect or even destroy the recorded data.
