A conducting rod is pulled horizontally with constant force F= 3.90 N along a set of rails separated by d= 0.440 m. A uniform magnetic field B= 0.500 T is directed into the page. There is no friction between the rod and the rails, and the rod moves with constant velocity v= 4.80 m/s. Using Faraday's Law, calculate the induced emf around the loop in the figure that is caused by the changing flux. Assign clockwise to be the positive direction for emf.
