MCQ
Which among the following is true about magnetic susceptibility?
  • A
    It is the ratio of magnetic intensity to intensity of magnetization.
  • B
    The SI unit of magnetic susceptibility is Tesla $(T).$
  • ✓
    It is the ratio of intensity of magnetization to magnetic intensity.
  • D
    It is the ratio of magnetic moment to volume.
✓

Answer

Correct option: C.
It is the ratio of intensity of magnetization to magnetic intensity.

Magnetic susceptibility of a magnetic substance is defined as the ratio of the intensity of magnetization $(I)$ to the magnetic intensity $(H).$ The expression is given by:
$\text{Xm}=\frac{\text{I}}{\text{H}}$
Magnetic susceptibility measures the aptness of a magnetic substance to acquire magnetism. It is a unit less constant of magnetic substance.
