Question

2. A rectangular loop of wire, with dimensions shown in the figure helow carries a current of 2.0 A and is placed in a 0.80 T magnetic field. The magnetic field runs horizontally from left to right in the plane of the paper. The loop rotates in the magnetic field. Assume that the dimensions given in the figure are exact. (a) At one point in its rotation, the loop is perpendicular to the magnetic field. What is the magnitude of the torque acting on the loop at this point? (b) As it rutates, the loop reaches a point where the normal to the plane of the loop makes a 30 angle with respect to the magnetic ield. What is the magnitude of the torque acting on the loop at this point
