The triangular coil of wire in the drawing is free to rotate about an axis that is attached along side AC. The current in the loop is 4.94 A, and the magnetic field (parallel to the plane of the loop and side AB) is B = 1.7 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?
