1) Do not approach electronic devices with neodymium iron boron magnets, as the magnets themselves have positive and negative poles and have a circuit loop. If approached, it will affect the electronic devices and control circuits, affecting their use.

2) Magnets should not be stored in damp environments to prevent oxidation, which may cause changes in appearance, physical properties, and magnetic properties.

3) People who have sensitive reactions to metal objects may have rough and reddish skin when they approach magnets. If the above reaction occurs, please do not touch the magnet.

4) Do not place magnets near floppy disks, hard drives, credit cards, magnetic tapes, memory cards, TV tubes, etc. If the magnet is placed close to devices such as magnetic recorders, it can affect or even damage the recorded data.

Pay attention to the following aspects:

1. Magnets should never be placed around strong currents;

2. Magnets should not be baked on fire and subjected to high temperatures;

3. Magnets cannot be subjected to impact or severe vibration;

4. Small magnets cannot be placed together with large magnets;

5. A hoof shaped magnet should also add a piece of soft iron to the two poles to connect them, and invert the north and south poles of adjacent magnets;

6. Small magnets (such as magnetic needles) cannot be placed together with large magnets.

When storing neodymium iron boron magnets, the requirement for the environment is to be dry, and also to prevent neodymium iron boron magnets from encountering chemicals such as acid and alkali, so as not to be affected,
