    Magnetic materials can be classified based on their dipole moment and response to external magnetic fields. Diamagnetic materials have no permanent dipole moment and are weakly repelled by magnetic fields, while paramagnetic, ferromagnetic, antiferromagnetic, and ferrimagnetic materials have a permanent dipole moment and are either non-magnetic or attracted to magnetic fields. Ferromagnetic materials are strongly attracted to magnetic fields and can retain their magnetic properties after the external field is removed.

    Classification of Magnetic materials

     Magnetic materials can be classified based on existence


    of dipole moment and the response to external
    magnetic fields
    Dipole Moment
     Diamagnetic materials – No permanent magnetic
    moment
     Para, Ferro, Anti-ferro, Ferri magnetic materials –
    possess permanent magnetic moment.

    Response To External Magnetic Fields


     Dia and para are non-magnetic
     Ferro, anti-ferro an ferri are magnetic materials
