Physics - Magnetism Question with Solution | TestHub

Areal vectors will be ⊥ to the plane.
Area vector is at$60^{\text{o}}$angle with x-axis and$30^{\text{o}}$angle with -z-axis.

$\overrightarrow{\text{M}}=\text{NI}\overrightarrow{\text{A}}$

$\overrightarrow{\text{M}}=10\times 10^{-2}\text{A } {\text{m}}^2$

$\text{M}=0·1\text{A } {\text{m}}^2$

$\overrightarrow{\text{M}}={\text{M}}_{\mathrm{x}}\hat{\text{i}}-{\text{M}}_{\mathrm{z}}\hat{\text{k}}=\text{Mcos}60\hat{\text{i}}-\text{Mcos}{30}^{\text{o}}\hat{\text{k}}$

$\overrightarrow{\text{M}}=\text{0.05}\left(\widehat{\text{i}}-\sqrt{3}\widehat{\text{k}}\right)$
