04.42: A solenoid is ) /35z gzkw n36mtpr n:y(-wntoozdr8 oriented end ww377 jod5bs8saa a6h-on so that its opening is perpendicular to the circuit containing the two light bulbs as drawn in figure C1. For figures C2 and C3, a shorting wire of negligible resistance is added as shown. Assume that the magnetic field from the solenoid, shown coming out of the plane of the page, decreases uniformly aba hwj8ao ss6d53 77win time at the same rate for each circuit. Rank the circuits for the brightness of the bulb labeled R1 from brightest to dimmest.
A. C1 > C3 > C2
B. C1 > C2 = C3
C. C2 > C3 > C1
D. C3 > C1 > C2
