A metallic ring is attached with the wall of a room. When the north pole of a magnet is brought near to it, the induced current in the ring will be

As shown in the figure, a magnet is moved with a fast speed towards a coil at rest. Due to this
induced electromotive force, induced current and induced charge in the coil is E, I and Q
respectively. If the speed of the magnet is doubled, the incorrect statement is

Lenz’s law is a consequence of the law of conservation of:-

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 :-

Two coils carrying current in opposite direction placed co-axially as shown in figure. Now that
brought closer to each other, than :-

Using Lenz’s Law, determine the direction of current flow in the loop for each of the two
situations shown below.

A conducting wire frame is placed in a magnetic field which is directed into the paper. The magnetic field is increasing at a constant rate. The directions of induced current in wires AB and CD are :-

A square coil ACDE with its plane vertical is released from rest in a horizontal uniform
magnetic field B of length 2L. The acceleration of the coil is :

A vertical bar magnet is dropped from position on the axis of a fixed metallic coil as shown in fig – I. In fig.II the magnet is fixed and horizontal coil is dropped. The acceleration of the magnet and coil are a1 and a2 respectively then

Two identical coaxial circular loops carry a current i each circulating in the same direction. If the loops approach each other
