A short coil with a cross-sectional area S = 150 cm2, containing N = 200 turns of wire carrying a current of force I = 4 A, is placed in a uniform magnetic field of intensity H = 8000 A/m. Find: 1) magnetic moment rm of the coil; 2) torque M acting on the coil from the field side, if the coil axis makes an angle φ = 60° with the field lines.
