A neodymium magnet (also, known as a rare-earth magnet) is a powerful magnet made of a combination of neodymium, iron, and boron Nd2Fe14B. These magnets are known to be installed in angular head motors and computer hard drives. Neodymium magnets are also popular with hobbyists, and a small magnet can have amazing properties it exhibits magnetic braking when moved near a non-magnetic metal due to induced eddy currents.Neodymium magnets should always be handled carefully.hey are hazardous, being able to pinch skin or fingers when suddenly attracted to a magnetic object. Because they are made with special powders and coatings, the magnets are very fragile and break at temperatures over 150 C, or if allowed to smash together. When they break, the magnets may break so suddenly that flying pieces may cause eye injury. Neodymium magnets should also be stored away from electrical appliances, credit cards and computer monitors, as damage may be irreparable.
