A wire is bent in the form of a `V` shape and placed in a horizontal plane.There exists a uniform magnetic field `B` perpendicular to the plane of the wire. A uniform conducting rod starts sliding over the `V` shaped wire with a constant speed v as shown in the figure. If the wire no resistance, the current in rod wil

An irregular shaped wire PQRS placed in a uniform magnetic field perpendicular to the plane of the paper changes into a circular shape. What will be the direction of the induced current in the loop.

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 wire is bent to form the double loop shown in figure. There is a uniform magnetic field directed into the plane of the loop. If the magnitude of this field is decreasing current will flow from:
