Question

Pick out the expression for intensity of magnetization from the following.

(a) I = \(\frac {M^2}{V}\)

(b) I = \(\frac {M}{V^2}\)

(c) I = \(\frac {V}{M}\)

(d) I = \(\frac {M}{V}\)

I had been asked this question during an online exam.

I would like to ask this question from Magnetisation and Magnetic Intensity in section Magnetism and Matter of Physics – Class 12

Answer 1

Correct choice is (d) I = \(\frac {M}{V}\)

For explanation I would say: Intensity of magnetization is defined as the magnetic moment developed per unit volume, when a magnetic specimen is subjected to the magnetizing field. Intensity of magnetization is denoted by I. The expression is given by:

I=\(\frac {M}{V}\)
