A flat wire coil with 15 turns and cross-sectional area of 0.05 meters squared, and a total resistance of 15 ohms, is placed in a magnetic field of 0.9 T, so that the normal to the plane of the coll lines up with the magnetic field. Then the coll is turned by 90 degrees so that the field lines are parallel to the plane of the coil. An ammeter of negligible internal resistance is used to measure the current flowing through the loop, and to deduce the total charge that flows through the coil while the call is turned from its initial to its final position. Assuming that during the turn the magnetic flux varies at a steady rate, calculate the total charge that flows through the circuit during the turn. 0.30 C 0.15 C 0.045 C 0.009 C 0.005 C
