1. The neodymium iron boron magnet is particularly strong in magnetism. It should first be avoided by the hand or other parts of the body being clamped by the magnet. For large magnets, it is necessary to pay more attention to safety.

2. Do not connect strong magnets to patients with electronic medical devices or devices that carry pacemakers.

3. Do not swallow powerful magnets. If swallowed, medical treatment should be taken immediately. Keep strong magnets out of the reach of children.

4. When using the magnet, the environment should be cleaned as much as possible to avoid the adsorption of fine impurities such as iron filings on the surface of the magnet. When the chips fly into the eyes, they can cause injury and must be used with care.

5, NdFeB Magnets should be stored in a ventilated and dry environment, acidic, alkaline, organic solvents, salt water, high temperature and humidity environment will easily oxidize the magnet, the plating layer will fall off, the magnet will be powdered demagnetization.

6. After the magnet is heated at high temperature, the magnetic properties will be attenuated. Please refer to the temperature resistance guidelines for the corresponding performance of the magnet. Note that the temperature should not be too high for the standard operating temperature when the magnet is assembled or used.

7. Neodymium iron boron magnets are brittle, so when used for vibration, shock, etc., there is a possibility of breakage or shedding. Always pay attention to collisions during use.
