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)?

10) need answer asap One hundred turns of insulated copper wire are wrapped around an iron core of cross-sectional area 0.300 m^2. As the magnetic field along the normal to the plane of the coil changes from 6.00 T to 15.00 T in 9 milliseconds, calculate the induced emf?
457 turns of insulated copper wire are wrapped around an iron core of radius 17.91 cm. The circuit is completed by connecting the coil to a 126.42 resistor. The magnetic field along the coil axis is made to change from 0.1673 T in one direction to 0.6368 T in the other direction. Calculate the total charge that flows through the resistor in this process. NOTES: 1. Note that the question asks for charge, not current 2. Be careful of your...
