One hundred turns of (insulated) copper wire are wrapped around a wooden cylindrical core of cross-sectional area 1.20 x 10-3 m2. The two ends of the wire are connected to a resistor. The total resistance in the circuit is 13.0Ω. If an externally applied uniform longitudinal magnetic field in the core changes from 1.60 T in one direction to 1.60 T in the opposite direction, how much charge flows through a point in the circuit during the change?
