Magnets are very useful and interesting, but they are not without dangers, especially neodymium magnets. Please read the following advice before handling or using magnets.
1. There is a risk of cracking or chipping
Neodymium magnets have very strong magnetic force. Put two magnets together, even small ones, and they will attract each other, jump toward each other with great acceleration, and then slam together. This is the most common cause of magnet breakage and it is possible that one or both magnets may chip or break.
Due to the force exerted by the magnets, fragments from magnet collisions may fly into a person's eyes at high speeds, so we recommend that safety goggles be worn when handling multiple neodymium magnets. Splinters and broken magnets are sharp, so treat them with the same care as you would broken glass.
2. Danger to children
Children should always be supervised when handling or playing with magnets. Children who may have swallowed magnets should always stay away from magnets. It is common to see news of children eating magnets. If a large piece of magnet is swallowed, they will attract each other through the intestinal wall, get stuck and squeeze the digestive tract, causing severe swelling, which may even be life-threatening and require surgical treatment. It is best to keep all neodymium magnets out of the reach of children.
3. Crushed fingers or broken bones
Larger neodymium magnets can crush human fingers and break bones.
4. Magnetic sensitive items need to be kept at a safe distance
Neodymium magnets are ten times stronger than ordinary magnets, keep a safe distance (at least 20 cm) between the magnet and all objects that may be damaged by magnetism.
5. Affect the pacemaker
There is a general lack of understanding of how magnets affect cardiac arresters. The operation of a pacemaker will be affected by the proximity of the magnet.
Most pacemaker materials are made of metal, which needs to be protected from strong magnetic fields. Because under a magnetic field, the pacemaker will stop working due to the magnetic field. This will have a serious impact on patients during first aid work and cause unnecessary casualties. Therefore, it is recommended that you do not place magnets around the pacemaker
