The magnetic field at the centre of a current carrying circular coil of area ' $A$ ' is ' $B$ '. The magnetic moment of the coil is ( $\mu_0=$ permeability of free space)

$\frac{2 \mu_0 \pi^{1 / 2}}{\mathrm{BA}^{3 / 2}}$

$\frac{\mathrm{BA}^{3 / 2}}{\mu_0 \pi}$

$\frac{2 \mathrm{~B} \mathrm{~A}^{3 / 2}}{\mu_0 \pi^{1 / 2}}$

$\frac{\mathrm{B} \mathrm{A}^2}{\mu_0 \pi}$

Two identical current carrying coils with same centre are placed with their planes perpendicular to each other. If current $\mathrm{I}=\sqrt{2} \mathrm{~A}$ and radius of the coil is $R=1 \mathrm{~m}$, then magnetic field at centre is equal to ( $\mu_0=$ permeability of free space)

$\mu_0$

$\frac{\mu_0}{2}$

$2 \mu_0$

$\sqrt{2} \mu_0$
