The coil of wire in the drawing is a right triangle and is free to rotate about an axis that is attached along side AC. The current in the loop is I = 4.70 A, and the magnetic field (parallel to the plane of the loop and side AB) is B = 1.80 T. (a) What is the magnetic moment of the loop, and (b) What is the magnitude of the net torque exerted on the loop by the magnetic field?
