The magnetic moment produced in a substance of mass 5 gram is

6 \times 10^{-7} \mathrm{Am}^2

. If its density is

5 \mathrm{~g} / \mathrm{cm}^3

, then intensity of magnetization in

\frac{A}{m}

will be

View answer and explanation

Correct option: A

0.6

Option A (0.6) is correct because the intensity of magnetization is the magnetic moment per unit volume, and the volume is calculated from the mass and density.
