Warning and Cautions: The neodymium magnets we sell are very strong. They must be handled with great care to avoid personal injury and damage to the magnets. Fingers and other body parts can get severely pinched between two attracting magnets. Bones can be broken by larger magnets.
Neodymium magnets are also brittle. They can chip, crack or shatter if allowed to slam together. Gloves and eye protection glasses should be worn when handling these magnets because shattering magnets can launch pieces at great speeds and sparks may be produced.
The strong magnetic fields of neodymium magnets can also damage magnetic media such as floppy disks, credit cards, magnetic I.D. cards, cassette tapes, videotapes or other such devices. Electronics such televisions, VCR, computer monitors and other CRT displays can also be damaged.
Small children should not be allowed to play with neodymium magnets as they can be dangerous. Small magnets pose a choking hazard and should never be swallowed or inserted into any body part. Older children should be supervised.
One should avoid having constant contact with magnets of any size and keep a distance of at least 3 feet to large magnets. So it is with the iron items in your home, such as knife, spoons, and forks.
Never allow neodymium magnets near a person with a pacemaker or similar medical device. The strong magnetic fields of the magnets can affect the operation of such devices.
NEVER machining, drilling, sawing or other mechanical alterations on the magnets, not only magnets broken, but the dust from the magnets is very flammable and may release toxic fumes.
