Question
Which among the following is true about magnetic susceptibility?
✓
Answer
- 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.
