Neodymium magnets are well established as being the most powerful type of magnetic material available on the market. In addition to being powerful, they are also extremely versatile. Their combination of power and strength makes neodymium magnets desirable for use in a wide variety of applications.
Neodymium magnets are a type of rare earth magnet, named for the rare earth elements they are composed of. In addition to the rare earth element neodymium (Nd), the composition of neodymium magnets also includes the elements iron (Fe) and boron (B). Neodymium magnets offer the highest Br and Hci values, with Br referring to remanence (the strength of the magnetic field) and Hci referring to coercivity (a magnetic material’s resistance to demagnetization). Neodymium magnets have the highest maximum energy product, or MGOe, of any magnetic material.
Because neodymium magnets contain neodymium and iron, they are susceptible to corrosion. Because of this, neodymium magnets are typically coated with nickel or another material, such as zinc, copper, tin, epoxy, aluminum, silver, or gold. A standard neodymium magnet has a working temperature of up to 80°C, although special high temperature neodymium magnets are capable of withstanding temperatures up to 200°C.
Applications for Neodymium Iron Boron Magnets
There are many applications for neodymium magnets in the field of science, technology, and engineering. Many technological developments that we rely on today would be impossible if not for magnets, namely the strength of neodymium magnets. For example, in medicine, magnetic resonance imaging machines (MRIs) serve as an invaluable diagnostic tool. In more generalized applications, neodymium magnets are utilized in sensors, switches, and electronics such as computer hard drives.
Sensors and switches that rely on neodymium magnets to operate correctly can be found in all major modes of transportation, including airplanes, personal vehicles, and public transportation such as buses. While neodymium magnets have always been important to traditional modes of transportation, they are seen as even more of a critical resource as technological developments continue, such as in the case of electric vehicles. As consumer demand for electric vehicles increases, the demand for neodymium magnets is expected to grow as well.
Going beyond the examples mentioned here, there are countless other applications neodymium magnets are utilized in. Neodymium magnets can be found in ventilators, advanced military defense technology, consumer electronics, industrial holding applications, oil filters, automotive sensors, and more.
