Question

Ferromagnetism is different from paramagnetism because

• A. The atoms of a ferromagnetic material have net dipole moment whereas that of paramagnetic materials don’t.
• B. Ferromagnetic material gets attracted to stronger field whereas paramagnetic materials don’t.
• C. Ferromagnetic material gets attracted to weaker field whereas paramagnetic materials don’t.
• D. Ferromagnetic materials form domains whereas paramagnetic materials don’t.

Answer 1

The correct option is D Ferromagnetic materials form domains whereas paramagnetic materials don’t.

The atoms of both ferromagnets and paramagnets have net dipole moments and both of these get attracted towards stronger magnetic field. Ferromagnets form domains of atoms with dipole moment aligned in the same direction but paramagnets do not form such domains.
