A sliding wire of length 0.25 m and having a resistance of 0.5Omega moves along conducting guiding rails AB and CD with a uniform speed of 4m/s. A magnetic field of 0.5 T exists normal to the plane of ABCD directed into the page. The guides are short-circuited with resistances of 4 and 2Omega as shown.

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).
