Imagine a would where free magnetic charges exist. In this world, a circuit is made with a U shape wire and a rod free to slide on it. A current carried by free magnetic charges can flow in the circuit. When the circuit is placed in a uniform electric field. E perpendicular to the plane of the plane of the circuit and the rod is pulled to the right with a constant speed v, the "magnetic EMF" in the current and the direction of the corresponding current. arising because of changing electric flux will be (l is the length of the rod and c is speed of light).

A horizontal wire is free to slide on the verticle rails of a conducting frame as shown in figure. The wire has a mass m and length l and the resistance of the circuit is R .
