A circular coil of 50 loops and a diameter 20.0 cm is lying flat on a tabletop, and carries a clockwise current of 2.50 A. A magnetic field of 0.450 T, directed to the north and at an angle of 45 degrees from the vertical down through the coil and into the tabletop is turned on.
(a) What is the torque on the coil and
(b) which side of the coil (north or south) will tend to rise from the tabletop?
