The substance(s) in which the atoms do NOT form magnetic dipole is/ are calledI. ferromagneticII. paramagneticIII. diamagnetic
Correct answer: D. II and III.
- A. I only.
- B. III only.
- C. I and II.
- D. II and III.
Explanation
Diamagnetic substances are those in which the atoms do not possess a permanent magnetic dipole moment. When an external magnetic field is applied, a magnetic dipole moment is induced in the opposite direction of the applied field.

About Electrical Properties of Solids
Electrical properties of solids depend on their band structure, charge carriers and conductivity. The topic compares conductors, insulators and semiconductors, relates resistivity to temperature, and covers intrinsic and extrinsic semiconductors, donor and acceptor impurities, electron and hole conduction, and the formation of p-type and n-type materials.
