Neodymium Bar Magnets are utilized in many applications which require high magnetic power per pound. Some of these applications are computer hard drive designs, power generators, and electric cars. One kilogram or smaller of neodymium would be needed for a Toyota Prius. The first purely magnetic electric model airplane was created using this kind of magnet in the early 1990’s.
Neodymium Bar Magnets known as neodymium-iron-ore bar magnets produce strong magnetic fields by inducing strong electric currents into electrically conductive metals like iron and steel. These magnets work similar to strong permanent magnets, but in a non-magnetic form which allows them to be used both in the home and industry. It was observed that neodymium bar magnets which contain barium have the ability to induce strong permanent magnetic fields in ferromagnetic and optically conductive materials.
Neodymium has an electrical charge, similar to nickel which makes it very effective in insulating against extreme temperatures. The electrical charge of the material provides a non-magnetic field that can help insulate against electromagnetic interference. There are a number of neodymium Bar Magnet, which have an impressive power of induced current by using a variety of processes. Among these processes are:
