The figure shows the orientation of a rectangular loop consisting of 66 closely wrapped turns each carrying a
current I. The magnetic field in the region is (40 i) mT. The loop can turn about the y axis. If θ = 30°, a = 0.3 m,
b = 0.5 m, and I = {i] A, what is the magnitude of the torque exerted on the loop?
