A square coil with sides equal to 30 cm, composed of 20 turns, transports an electrical current of 3 A in an anti-clockwise direction, considering the plane of the coil the XY plane. This coil is then immersed in a uniform magnetic field of modulus equal to 12 T, in a direction and direction that represents an angle of 30° with the Z axis positive. Therefore, determine: (a) the magnetic moment of the coil; (b) the torque on the coil;
