1. The problem statement, all variables and given/known data

See attachment.

2. Haven't gotten there yet.

3.

The problem I'm having with this is seeing the connection between the capacitor (at least, that's what I assume that square thing is) and the loop. Frankly, I don't see why there would be or why there must be current in the loop at all. These are thought processes I've followed so far:

1. Energy stored in the capacitor implies there's a charge on the capacitor.

2. Charge on the capacitor implies that there is a voltage difference across the capacitor.

3. Voltage across capacitor causes a current in the loop...?

OR

1. Charged up capacitor means the current in the capacitor has stopped/is stopping.

2. Dwindling current implies a changing electric field.

3. Changing electric field induces a magnetic field in loop.

4. ???? somehow that relates to current in the loop?

It will take a day for your attachment to be approved. It would be better to upload the diagram to a free photo site like photobucket.com, then post a link to it here. If you put IMG before the link and /IMG after (both in square brackets), the diagram will appear right in the post.
