A rectangular coil of length 0.12 m and width 0.1 m having 50 turns of wire is suspended vertically in a uniform magnetic field of strength 0.2 weber/$m^2$. The coil carries a current of 2 A. If the plane of the coil is inclined at an angle of $30^\circ$ with the direction of the field the torque required to keep the coil in stable equilibrium will be 0.24 Nm 0.12 Nm 0.15 Nm 0.20 Nm
