A single-turn square loop of wire, 2.00 cm on each edge, carries a clockwise current of 0.170 A. The loop is inside a solenoid, with the plane of the loop perpendicular to the magnetic field of the solenoid. The solenoid has 30.0 turns/cm and carries a clockwise current of 15.0 A.
(a) Find the force on each side of the loop.
magnitude µN direction
(b) Find the magnitude of the torque acting on the loop.
