A hundred turns of insulated copper wire are wrapped around an iron cylinder of area `1xx10^(-3) m^(2)` and are connected to a resistor. The total resistance in the circuit is `10` ohms. If the longitudinal magnetic induction in the iron changes from `1` weber `m^(-2)`, in one direction to `1` weber `m^(-2)` in the opposite direction, how much charge flows through the circuit

One hundred turns of (insulated) copper wire are wrapped around a wooden cylindrical core of cross-sectional area 1.90 xx 10^(-3) m^(2) . The two ends of the wire are connected to a resistor. The total resistance in the circuit is 9.50 Omega . 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?
