A strong magnet is a neodymium iron boron magnet. Compared with ferrite magnets, AlNiCo, SmCo, the magnetic properties greatly exceed those of other magnets. NdFeB magnets can absorb 640 times their own weight, so NdFeB is often used by outsiders. It is called a powerful magnet.
1. Do not approach the electronic equipment with strong magnets. If it is close, it will affect the electronic equipment and control loop and affect the use.
2. Do not store the magnet in a humid environment to avoid oxidation, resulting in changes in appearance, physical properties and magnetic properties.
3. If a person who is sensitive to a metal object is close to the magnet, it will be rough and reddish. If the above reaction occurs, do not touch the strong magnet.
4. Do not place the magnet close to a floppy disk, hard drive, credit card, tape, debit card, TV picture tube, etc. If the magnet is placed close to a device such as a magnetic recorder, it will affect or even destroy the recorded data.
