Problem

A rectangular coil of 50 turns has dimensions

8\,\text{cm}\times4\,\text{cm}

and carries a current of

5\,\text{A}

. It is placed in a uniform magnetic field of

0.20\,\text{T}

such that the angle between the normal to the plane of the coil and the magnetic field is

30^{\circ}

. Calculate the magnitude of the torque acting on the coil.
