In solid state, the metal ions of ferromagnetic substances are grouped together into
small regions. These regions are called domains and each domain acts as a tiny magnet.
In an unmagnetised piece of a ferromagnetic substance, the domains are randomly
oriented. As a result, the magnetic moments of the domains get cancelled. However,
when the substance is placed in a magnetic field, all the domains get oriented in the
direction of the magnetic field and a strong magnetic effect is produced.
The ordering of the domains persists even after the removal of the magnetic field. Thus,
the ferromagnetic substance becomes a permanent magnet.
