Physics - Magnetism Question with Solution | TestHub

A coil having 100 turns, area of $5\times 10^{-3}{\mathrm{m}}^2$, carrying current of $1\mathrm{mA}$ is placed in uniform magnetic field of $0.20\mathrm{T}$ such a way that plane of coil is perpendicular to the magnetic field. The work done in turning the coil through $90^{\circ }$ is _______ $\mu \mathrm{J}$.
