Show Answer
Solution:
Ans. Diamagnetic specimen will move towards the weaker region of the field while paramagnetic specimen moves towards the stronger region. The diamagnetic specimen gets repelled by a magnet while paramagnetic specimen moves towards the magnet. Further, the paramagnetic gets aligned along $\mathrm{B}$ while diamagnetic remains perpendicular to the field.
