The dimensional formula for $\frac{1}{2}{\epsilon }_{\circ }{E}^2$ is identical to that of:

In a closed circuit of resistance $10\Omega$, the linked flux varies with time according to relation $\varphi =6t^2-5t+1 at t=0.25 sec$, the current(in Ampere) flowing through the circuit is:

What are Eddy currents? give its two uses.

When a magnet is moved towards a suspended wire loop as shown in figure then evaluate the direction of induced current in loop. State the law used by you for this evaluation.

The working of dynamo is based on the principle of-

Lenz's law of electromagnetic induction follows the principle of conservation of energy. Discuss it.

What is meant by mutual induction?
