Everyone knows that neodymium iron boron magnets are also called powerful magnets, so it is particularly important to preserve powerful magnets. How to preserve the magnets for a long time?

Neodymium iron boron magnets are currently very artificially made, because of their strong magnetic properties, they are called the most popular magnetic products on the market. Therefore, the protection methods that are not used for a long time are also problems that need to be solved. NdFeB magnets have spontaneous magnetization, so what should be paid attention to during storage?

1. Do not approach electronic equipment with neodymium iron boron magnets, as it will affect electronic equipment and control circuits and affect the use.

2. Do not store neodymium iron boron magnets in a humid environment to avoid oxidation, which may cause changes in appearance, physical properties and magnetic properties.

3. Do not bring magnets close to floppy disks, hard drives, credit cards, tapes, debit cards, TV picture tubes, etc. If the magnet is close to the magnetic recorder and other devices, it will affect or even destroy the recorded data.

4. The magnet cannot be knocked and vibrated severely; a piece of soft iron should be added to the two poles of the hoof-shaped magnet to connect the two poles, and the north and south poles of adjacent magnets should be inverted.

5. If a person who is sensitive to metal objects approaches the magnet, the skin will be rough and red. If the above reaction occurs, please do not touch strong magnets.

The magnetic material of the main neodymium iron boron magnet can be controlled within the normal range of the temperature resistance of the rare earth strong magnetic material, and the demagnetization of the neodymium iron boron magnet can be ignored.

When storing strong magnets, the general requirements for the preservation environment are relatively dry. It should also be noted that during the preservation process, do not let the strong magnet encounter chemicals such as acid and alkali, so as to avoid the magnetic material of the neodymium iron boron magnet. Corrosion, rust, etc. will occur, so we can place the NdFeB magnet on a layer of wood, which can effectively prevent moisture.
