shows a long U shaped wire of width l placed in a perpendicular magnetic field B. A wire of length l is slide on the U shaped wire with a constant velocity v towards right. The resistance of all the wires is r per unit length. At t =0, the sliding wire is close to the left edge of the U shaped wire. Draw an equivalent circuit diagram, showing the induced emf as a battery. Calculate the current in the circuit.
