Neodymium magnets are a type of permanent magnets also known as rare earth magnets, due to the fact that they contain one or more of the rare earth elements of the periodic table. Most are made of a metal alloy containing neodymium, iron, and boron. They are much stronger than most of the magnets people are accustomed to using, like refrigerator magnets. Because of the forces they generate, they can be dangerous or even cause fatal injury if not handled properly.

These magnets are the strongest permanent magnets available, and are able, in some cases, to hold up more than 1,000 times their own weight. They are manufactured in many different shapes and sizes, such as cubes, discs, spheres, plates, and rings, among others. Small ones are used in certain electronic devices, such as computer hard drives and headphones. They have also been found to be useful in the construction of engines for remote-controlled model aircraft.
