A segment of wire 7.5 cm long is moving at a velocity of 3.26 m/s toward a parallel (much longer) wire which carries a current of 3.46 A. At a particular instant the wire segment is 7.4 cm away from the long, current-carrying wire. What is the induced emf (voltage) between the two ends of the wire segment?
