Solution

The correct option is A $π R^{2} i$

Dipole moment is $μ = i A$ [A is area of loop]
$A = A_{1} + A_{2} = \frac{π R^{2}}{2} + \frac{π R^{2}}{2} = π R^{2}$
$μ = π R^{2} i$

Magnitude of magnetic dipole moment of loop as shown in figure is? Each curve is of radius R.

The correct option is A πR2i Dipole moment is μ=iA [A is area of loop] A=A1+A2=πR22+πR22=πR2 μ=πR2i

The correct option is A $π R^{2} i$

Dipole moment is $μ = i A$ [A is area of loop]
$A = A_{1} + A_{2} = \frac{π R^{2}}{2} + \frac{π R^{2}}{2} = π R^{2}$
$μ = π R^{2} i$
