Describe about the Ferromagnetic materials
Ferromagnetic materials are those for which k susceptibility is large and positive. These are strongly attracted by magnetic field. Illustrations are iron, cobalt, nickel etc.
A significant feature of ferromagnetic materials is that they can retain their magnetism even after magnetising field has been removed, i.e. they can become permanent magnets.
Ferromagnetic materials are those with spontaneous magnetic alignment. Ferromagnetism is property of a material to be strongly attracted to a magnetic field and to become a powerful magnet.
