2) A short section of wire, of length a, is moving with velocity v, parallel to a very long wire carrying a current L. The near end of the wire section is a distance b from the long wire. Assuming the vertical wire is very long compared to a+b, determine the emf between the ends of the short section, Assume v is in the opposite direction as I.
