Explanation:
Demagnetizing a magnet is also possible. Only a few substances are ferromagnetic; the most common ones are iron, cobalt and nickel and their alloys. The prefix ferro- refers to iron, because permanent magnetism was first observed in lodestone, a form of natural iron ore called magnetite, Fe3O4.
Every substance has some magnetic properties associated with it. The origin of these properties lies in the magnetic moments associated with the electrons. ... Thus electrons behave like tiny magnets. Thus, each electron has a permanent spin and an orbital magnetic moment associated with it
Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements iron, nickel and cobalt and their alloys, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone.
Magnetic Property of Solids. The magnetic properties of a solid are the result of the magnetic property of the atoms or ions of these solids. More specifically the magnetism and magnetization of a solid will depend on the movement of electrons in an atom.
