Aclosely wound search coil has an area of 3.20 cm2, 120 turns, and a resistance of 60.0 æ. it is connected to a charge-measuring instrument whose resistance is 45.0 æ. when the coil is rotated quickly from a position parallel to a uniform magnetic field to a position perpendicular to the field, the instrument indicates a charge of 3.56 * 10-5 c. what is the magnitude of the field?
