Permanent magnets (PMs)
Permanent Magnets (PMs) are materials where the magnetic field is generated by the internal structure of the material itself. PMs are directly linked and critical to the energy transition due to their applications in electric motors and wind power. They are made from special alloys (ferromagnetic materials) such as iron, nickel and cobalt, several alloys of rare-earth and minerals such as lodestone.
