TIPS:
1. When strong NdFeB magnets attrack magnets or any other iron,do not separate by force but horizontal pushing stagger, otherwise it is easy to cause damage to magnets and fingers.
2. Strong NdFeB magnet should be away from the iron and magnetized items, such as floppy disks, computer display (TV), bank cards, watches, mobile phones, medical devices and stay away from cardiac pacemaker, etc.
3. Strong NdFeB magnets are hard but brittle especially the thin pieces which should be stored in dry, constant temperature environment , separated and packed with plastic, wood, cardboard and foam.
