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?
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.
