Question

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)

(c) It is the ratio of intensity of magnetization to magnetic intensity

(d) It is the ratio of magnetic moment to volume

The question was asked in examination.

My question is from Magnetic Properties of Materials topic in division Magnetism and Matter of Physics – Class 12

Answer 1

Right option is (c) It is the ratio of intensity of magnetization to magnetic intensity

The best explanation: 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:

χm=\(\frac {I}{H}\)

Magnetic susceptibility measures the aptness of a magnetic substance to acquire magnetism. It is a unit less constant of magnetic substance.
