(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The wire shown is being pulled through a constant magnetic field of 0.25 Tesla at 3 m/s.

A) Find the power required to pull the loop at this speed.

B) If the wire has a resistance of 100 ohms, what is the current in the wire?

2. Relevant equations

3. The attempt at a solution

I am trying to teach myself this problem, as I missed a week of school because of a back surgery and the slides I was given are wholly inadequate. I am not looking for a simple solution, but an explanation and a little bit of guidance to point me in the right direction would be stupendous.

This isn't a homework problem (as in it has a due date) but it is in the back of the book and is listed as difficult.

The picture (I have drawn) is here: http://twitpic.com/7e6nad [Broken]

Thank you all.
