Question

The magnetic moment of a magnet of dimensions 5 cm × 2.5 cm × 1.25 cm is 3 Am². Calculate the intensity of magnetization.

Answer 1

Intensity of magnetization I = M/V where,

M = magnetic moment

V = volume

V = 5 × 10^-2 × 2.5 × 10^-2 × 1.25 × 10^-2

V = 1.5625 × 10^-5 m³

I = M/V

I = 3/1.5625 × 10^-5

I = 1.92 × 10⁵ A-m
