1. The problem statement, all variables and given/known data The metal rod in the figure moves with speed v parallel to a straight wire that is carrying current I. The distance between the two wires is d, as shown in the figure. If the end of the rod closest to the wire is chosen to be at zero potential, what is the potential at the end of the rod furthest from the wire? Give your answer in terms of I, v, d, l, and constants u0 and pi. 2. Relevant equations N/A 3. The attempt at a solution I don't even know where to start with this question.
