Quiz 6 -- Magnetic Force/Torque

The figure below shows a rectangular, 20-turn coil of wire, 10.0 cm by 5.0 cm. It carries a current of 0.10 A and is hinged along one side. It is mounted in the xy plane, at an angle of 30 degrees to the direction of a uniform magnetic field of 0.50 T. Find the magnitude and direction of the torque acting on the coil about the hinge line.
