Ferromagnetic materials are materials that exhibit strong magnetization and can retain magnetic properties even after the external magnetic field is removed. These materials are primarily obtained from iron (Fe), cobalt (Co), and nickel (Ni). They have aligned magnetic domains, which give rise to permanent magnetism, and are widely used in electromagnets, transformers, and data storage devices.
