Answer
Ferromagnetic metals maintain their magnetic properties when they are removed from the magnetic field.
Para-magnetic metals loose their magnetic properties when they are removed from the magnetic field.
Work Step by Step
Ferromagnetic metals are those metals which are magnetized when placed in a magnetic field and they maintain their magnetic properties when they are removed from the magnetic field.
Para-magnetic metals are those metals which are magnetized when placed in a magnetic field but loose their magnetic properties when they are removed from the magnetic field.
