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)?

A circular coil enclosing an area of 97 cm2 is made of 201 turns of copper wire. The wire making up the coil has resistance of 6.0Ω, and the ends of the wire are connected to form a closed circuit. Initially, a 1.7 T uniform magnetic field points perpendicularly upward through the plane of the coil. The direction of the field then reverses so that the final magnetic field has a magnitude of 1.7 T and points downward through the...
