The correct answer is:
Ferromagnetic
Magnetic susceptibility is a dimensionless quantity. It indicates degree of magnetisation of material in response to an
applied magnetic field. For the given magnetic material susceptibility is \( 400 \). Since the susceptibility is positive and
possess permanent magnetisation, therefore, material is ferromagnetic.
