Neodymium magnets are the strongest permanent magnets on Earth. Due to their various characteristics they have many uses but need to be handled with extreme care and precision to prevent accidents.
Here are some safety guidelines to follow when working with Neodymium magnets.
- When working with Neodymium magnets take care to protect your hands and fingers and handle the magnets with care. Two attracting magnets can severely pinch your fingers if they come between the magnets. The feeling would be no less than having your fingers being pressed between a pair of pliers.
- Free floating Neodymium magnets can slam together with great force. As they are brittle in nature they can often peel, crack or shatter and send shards of magnets flying all over the place. Hence it is essential to wear eye protection when handling Neodymium magnets.
- Neodymium magnets have strong magnetic fields. Thus, if left near magnetic media like computers, floppy disks, hard drives, credit cards, magnetic I.D. cards, cassette tapes and video tapes these magnets are likely to cause damage. Neodymium magnets should also never be left near electronic devices like televisions, computer monitors and VCRs unless you want to have to replace the device with a new one.
- Children should never be allowed to handle Neodymium magnets. Other than the fact that they pose a choking hazard because of their small size, small body parts can get pinched between two magnets and hurt the child.
- Neodymium magnets should also not be allowed near a person who uses medical aids like a pacemaker. The magnet can cause the medical aid to malfunction.
- Neodymium magnets are brittle and prone to cracking and chipping. Hence they do not take well to machining. Only special machines can handle Neodymium magnets and under the supervision of experts.
- Neodymium magnets should never be heated above 175 o F or 80o C as they will loose their magnetic properties. In addition, they may catch fire and burn and produce toxic fumes.
Thus, Neodymium magnets have many industrial, education and household uses but only when handled with extreme care and precaution.
