You are correct, fluid. By Lenz's Law, the current would be pointing down and thus negative due to the fact the conducting bar is moving away from the wire. If the opposite were the case, the final result would be positive. As for my final, the teacher didn't put anything like this on it...

Can any experts confirm my answer as correct?

Well fluid, I appreciate you looking it over! I know for a fact this will be on my final tomorrow and I'm currently studying. This problem seems easy enough using Faraday's law but I hope they way I did it was correct. I wish I was just better at physics than I am. :cry:

Also, did I skip any steps?

Alright, how does this look: E = -d/dt*(Flux B) E = -d/dt * BLR E = dr/dt * -BL E = -BLV E = -u_o*I*V*L / 2*pi*r Why does the negative go away for the correct answer?

A conducting rod moves with a constant velocity v in a direction perpendicular to a long, straight wire carrying a current I as shown in the figure below. Find the EMF It should equal U_o*V*L*I/2*pi*r, but how do I get there?
