04.42: A solenoid is oriented end-on 9jw/( mxke ;ygi9x:h sso that its opening is perpend jo0odjl 8gygmcxr 54f c2*c*6icular to the circuit containing the two 5j8y d*olc0mr 2*foc cgxj 6g4light 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 in 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
E. C3 = C2 = C1
