Paramagnetic substance

  1. When a para magnetic substance is brought near a north pole or a south pole of a bar magnet it
    experiences attraction. How?

    Hint : when you put the para magnetic substance in external magnetic field it magnetize. So it experiences the resultant force towards the stronger magnetic field.

    Paramagnets in external magnetic fields acquire a net average magnetic dipole moment due to the thermal averaging over the unpaired spins of the atoms in the magnet coupled to the external field.
