1. A 25.0 m metal rod moves at a speed of 5 m/s perpendicular to a magnetic field of intensity 1.4 T. Find the resulting potential difference at the ends of the rods. 2. A square loop with 5 cm sides is perpendicular to a uniform field 150 mT in intensity. If a third of this flux remains every 0.010 s, what is the average emf induced?
