Answer 1

The magnetic moment produced in a substance of mass 5 gram is 6 x 10^-7 Am² If its density is 5 g/cm³, then intensity of magnetization in ${\displaystyle \frac{\text{A}}{\text{m}}}$ will be 0.6.

Explanation:

Mass = 5 g, density = 5 g/cm³

${\displaystyle \text{Volume V}=\frac{\text{mass}}{\text{density}}=\frac{5\text{g}}{5\text{g}/{\text{cm}}^3}=1 {\text{cm}}^3={10}^{-6} {\text{m}}^3}$

${\displaystyle \text{magnetization}=\frac{\text{magnetic moment}}{\text{volume}}}$

${\displaystyle =\frac{6\times {10}^{-7}}{{10}^{-6}}}$

${\displaystyle =0.6 \text{A/m}}$
