As shown in the figure, a metal bar of length l= 0.25 m is free to slide on frictionless rails. A uniform magnetic field B= 2.8 T, perpendicular to the plane of the rails and pointing outward from the page, is present. The bar is in a downward motion with a velocity of magnitude v=2 m/s. What is the magnitude and direction of the induced current through the resistor R=4 ohms O BO R
