Hello, can somebody help me with this? Please make sure your writing, explanation, and answer is extremely clear.
A short section of wire, of length a, is moving with velocity v, parallel to a very long wire carrying a current I as shown in the figure. 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. (Figure 1)
