While the two parallel ends shown in the figure are connected to each other with a metal rod, the other two ends are free. A conductive rod can slide freely on the rails.The speed of the stick is constant.In the figure, there is a magnetic field perpendicular to the plane and in the direction of which the size is 35 tesla.a) Since the distance between the rails is 25cm and the speed of the conductor rod is 55cm / sec, find the emk formed in the abcd frame consisting of the rail and the conductor rod.b) The resistance of the conductive rod is 18 ohms.
