Physics - Current Electricity Question with Solution | TestHub

A single turn circular coil of radius 3 m produces a magnetic field of $9\pi \mu \mathrm{T}$ at a point 4 m away from its center at a point on its axis. If it is kept in a uniform magnetic field of $\frac{1}{125\pi }\mathrm{T}$ whose direction makes an angle of $60^{\circ }$ with its plane, find its initial angular acceleration (in rad/ ${\mathrm{s}}^2$ ). The mass of the coil is 1 kg .
