In the circuit above the battery has a voltage of n2 Volts. Note that
the left side of the battery is positive. The resistor in the circuit has a resistance
of n1 Ω. There is a magnetic field that points into the page and is
increasing in time. This causes the magnitude of the flux to increase at the rate
|Φ| = 10 t Volt-Sec. What is the current in the circuit, if
positive current means flowing in the direction of the arrow? That is, if
I = n3 Amp, what is n3?
