(27-37) A circular coil 18.0cm in diameter and containing twelve loops lies flat on the ground. The Earth’s magnetic field at this location has magnitude 5.50×10^−5T and points into the Earth at an angle of 66.0^° below a line pointing due north. If a 7.10A clockwise current passes through the coil, determine (a) the torque on the coil, and (b) which edge of the coil rises up, north, east, south, or west.
