*Neodymium magnet can be very dangerous. Body parts especially fingers can get severely pinched between two attracting magnets,so you need to handle them carefully to avoid personal injury.
*Neodymium magnets are brittle and prone to chipping and cracking. They can peel, crack or shatter if allowed to slam together. Machining, drilling or other mechanical alterations are not recommended. And eye protection is necessary when handling these magnets.
*As the strong magnetic fields of neodymium magnets can damage or affect the operation of magnetic media and medical devices, never allow neodymium magnets near a person with these kind of devices.
*Children should not be allowed to play with neodymium magnets as small magnets pose a choking hazard.
