I posted this question a few months ago, but got no responses, especially after it got moved to the homework help forum. Since then, I have asked several professors, many of whom I expected to be experts in this area, and I've been given several different shaky sounding responses. So, I'd like to have a discussion about it. This is not a homework problem. It is simply a thought experiment.
Here's the picture:

In the picture, the inner circle represents a solenoid producing a decreasing (over time) magnetic field pointing uniformly out of the screen. A wire loop with two lightbulbs in series is placed above the solenoid (the outer circle). The changing B-field produces an EMF in the wire as shown. Next, a segment of wire is connected to this wire loop as shown by the thick black line.
The question is, what happens when you connect this wire segment?
I've gotten answers from, both lightbulbs going off, to nothing happening, to one lightbulb going off, to both bulbs dimming, and now I'm just confused and I'm starting to think I don't understand inductance at all... if anyone has some words of wisdom on this one, it would be a load off my mind.
thanks.
