Options
- ATheir magnetic susceptibility is small and negative.
- BThe material moves from a region of strong magnetic field to weak magnetic field.
- CDiamagnetic materials are repelled by bar magnets.
- DThe origin of diamagnetism is the spin of electrons.
Correct answer
D. The origin of diamagnetism is the spin of electrons.
Step-by-step solution
Diamagnetic materials exhibit a small negative magnetic susceptibility, denoted as When placed in a non-uniform magnetic field, diamagnetic materials are weakly repelled, meaning they move from a region of stronger magnetic field to a region of weaker magnetic field. Diamagnetic materials are repelled by bar magnets due to the induced magnetic moment being in the opposite direction to the applied field. The origin of diamagnetism is the orbital motion of electrons, which creates an induced magnetic moment opposing
