Thanks for the quick reply. I'm just a tad confused about your notation. Are you saying that in this case I = 2\xi/R? Or that if the emf is known, then it is always simply I=\xi/R? Edit: Oh, ok. I didn't see your edit there. Thanks for the help.

I'm working on a question that I could use some help on. The problem basically says there is a solenoid with a current running through it given by an equation. There is a wire that is coaxial with and surrounding the solenoid, and the wire makes two loops around the solenoid. A resistance for...

Hi, I've been trying to figure out this problem for a while now and I could use some help. The problem reads "An electron and proton attract each other with a 1/r^2 electric force, just like the gravitational force. Suppose that an electron moves in a circular orbit about a proton. If the...
