Alalisemagnet

Alalisemagnet is an Estonian term that translates to "permanent magnet" in English. A permanent magnet is a magnet that generates its own magnetic field without being magnetized by an external electric current. These magnets are made from materials that are permanently magnetized, meaning they retain their magnetism over time. Common materials used for permanent magnets include ferrite, neodymium-iron-boron (NdFeB), samarium-cobalt (SmCo), and Alnico (an alloy of aluminum, nickel, and cobalt).

The magnetic properties of a permanent magnet are determined by its composition and how it is manufactured. When exposed to a strong magnetic field during production, the magnetic domains within the material align, creating a net magnetic moment. This alignment is then "frozen" in place, resulting in a persistent magnetic field. Alalisemagnetid are ubiquitous in everyday life, found in electric motors, generators, loudspeakers, magnetic data storage devices, compasses, and many other applications where a constant magnetic force is required. Their strength and properties vary depending on the specific material used.
