If the atoms of a material possess a non-zero permanent magnetic moment, then the material

Options

  1. Amust be diamagnetic
  2. Bmust be ferromagnetic
  3. Cmay be paramagnetic
  4. Dmust be paramagnetic

Correct answer

C. may be paramagnetic

Step-by-step solution

Atoms of diamagnetic materials have zero permanent magnetic moment. Atoms of paramagnetic and ferromagnetic materials possess a non-zero permanent magnetic moment. Therefore, if the atoms of a material possess a non-zero permanent magnetic moment, the material can be either paramagnetic or ferromagnetic. Thus, the material may be paramagnetic.
