One hundred turns of insulated copper wire are wrapped around a wooden cylindrical core of cross-sectional area 1.30×10-3 m2. The two terminals are connected to a resistor. The total resistance in the circuit is 15.0 O.
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 the circuit (in Coulombs)?
