The correct answer is:
$1.6$
Volume of the sample $\mathrm{V}=\frac{\text { mass }}{\text { density }}=\frac{2}{4}=0.5 \mathrm{~cm}^{3}=0.5 \times 10^{-6} \mathrm{~m}^{3}$
Magnetization $=\frac{\text { Magnetic moment }}{\text { Volume }}=\frac{8 \times 10^{-7}}{0.5 \times 10^{-6}}=1.6 \mathrm{~A} / \mathrm{m}$
Magnetization $=\frac{\text { Magnetic moment }}{\text { Volume }}=\frac{8 \times 10^{-7}}{0.5 \times 10^{-6}}=1.6 \mathrm{~A} / \mathrm{m}$
