Choose the correct statement:

Options

A. A paramagnetic material tends to move from a strong magnetic field to weak magnetic field.
B. A magnetic material is in the paramagnetic phase below its Curie temperature.
C. The resultant magnetic moment in an atom of a diamagnetic substance is zero.
D. Typical domain size of a ferromagnetic material is 1 nm.

Answer

C

Explanation

Diamagnetic substances are those substances in which resultant magnetic moment in an atom is zero.

A paramagnetic material tends to move from a weak magnetic field to a strong magnetic field.

A magnetic material is in the paramagnetic phase above its Curie temperature.

Typical domain size of a ferromagnetic material is 1 mm. The susceptibility of a ferromagnetic material is
