A flat rectangular coil 5.20 cm by 10.5 cm contains 34.0 turns of wire. If the coil is placed in a uniform magnetic field, B = 0.0640 T, and it carries a current, I = 2.60 A, calculate the maximum torque exerted on the coil by the magnetic field. For maximum torque should the field be parallel to the plane of the coil or perpendicular to the plane of the coil?
