Not All Iron Is Magnetic (Magnetic Elements)

Iron is magnetic in its α form. The α form occurs below a special temperature called the Curie point, which is 770 °C. Iron is paramagnetic above this temperature and only weakly attracted to a magnetic field. Magnetic materials consist of atoms with partially-filled electron shells. So, most magnetic materials are metals. Other magnetic ...
