A square coil of side 10 cm consists of 20 turns and carries a current of 12 A. The coil is suspended vertically and the normal to the plane of the coil makes an angle of 30º with the direction of a uniform the horizontal magnetic field of magnitude 0.80 T. What is the magnitude of torque experienced by the coil?
Magnitude of torque experienced by coil in the magnetic field is given by, τ=nBIAsinθ=0.96 Nm where A=l×l
