Physics - Magnetism Question with Solution | TestHub

$L=3 \text{cm}=3\times {10}^{-2} \text{m}$

$A=2 {\text{cm}}^{\text{2}}=2\times {10}^{-4} {\text{m}}^{\text{2}}$

$M=3\mathrm{ }\mathrm{A} {\mathrm{m}}^2$

$M_z\to$Intensity of magnetization

$$\begin{gathered} =\frac{M}{L\times A}=\frac{3 {\text{A m}}^{\text{2}}}{3\times 2\times {10}^{-6} {\text{m}}^{\text{3}}} \\ =\frac{1}{2}\times {10}^6 {\text{A m}}^{-1}=5\times {10}^5{\text{A m}}^{-1} \end{gathered}$$
