A square, current-carrying loop is placed in a uniform magnetic field with the plane of the loop parallel to the magnetic field (see the drawing). The dashed line is the axis of rotation. The magnetic field exerts _______.
(a) A net force and a net torque on the loop
(b) A net force, but not a net torque, on the loop
(c) A net torque, but not a net force, on the loop
(d) Neither a net force nor a net torque on the loop
