Use Tips:
Neodymium magnets are most strongest magnet in the nature. So it may be
dangerous. Therefore must be handled with care to avoid personal injury and damage
to the magnets. Fingers and other body parts can get severely pinched between two
attracting magnets. Neodymium magnets are brittle, and can shatter if allowed to slam
together, launching small pieces at great speeds. Eye protection should be worn when
handling there magnets.
