Have you noticed these places when using them? 1. The magnetism of neodymium iron boron magnets is very strong. You should first avoid using magnets to grip your hands or other parts of your body. For large-sized strong magnetism, you need to pay more attention to safety. 2. Do not connect strong magnets to patients near electronic medical devices or carrying pacemakers and other devices. 3. Do not swallow strong magnets. If swallowed accidentally, immediate medical attention should be sought. Strong magnets should be placed out of reach of children. 4. During the use of magnets, the environment should be kept as clean as possible to avoid small impurities such as iron filings adsorbing on the surface of the magnet and affecting its use. Magnetic debris flying into the eyes can cause injury and requires careful use. 5. Neodymium iron boron magnets should be stored in a ventilated and dry environment. Acidic, alkaline, organic solvents, saline water, and high-temperature and humid environments can easily oxidize magnets, cause the plating to fall off, and cause the magnets to be crushed and demagnetized. 6. The magnetism of a magnet will decay when heated at high temperatures. Please refer to the temperature tolerance guide to understand the corresponding performance of the magnet. When assembling or using the magnet, be careful not to exceed the standard operating temperature. 7. Neodymium iron boron magnets are fragile, so when used in fields such as vibration and impact, they may break or fall off. Be sure to pay attention to collisions when using.
