A circular coil 17.0 cm in diameter and containing eleven loops lies flat on the ground. The Earth's magnetic field at this location has magnitude 5.5 ? 10-5 T and points into the Earth at an angle of 56° below a line pointing due north. Assume a 7.8 A counterclockwise current passes through the coil.
(a) Determine the magnitude of the torque on the coil.
