Neodymium Magnets Safety And Handling Guidelines
Neodymium Magnets are very strong and powerful. Their magnetic power allows them able to generate some magic effect. They are interesting but are not toys. Their special physical properties determine that they are easy to be damaged in magnetic characteristics and need to be handled with extreme care and precision to prevent accidents.
Here following are some guidelines about and safe operation, storage, transportation and disposal for this type of rare-earth magnets.

Neodymium magnets are brittle and prone to cracking and chipping. Hence they should be machined in professional methods and by special machines. The supervision of experts or professional technicians is also vital during the machining and operation.

When working with Neodymium magnets, take care to protect your hands and fingers. Two attracting magnets can severely pinch your fingers if they come between the magnets, which may make you feel no less than having your fingers pressed between a pair of pliers.
