Question

Explain Faraday’s law of induction with the help of activity.

Answer 1

Faraday's experiment showing induction between coils of wire: The liquid battery(right)provides a current which flows through the small coil(A), creating a magnetic field. When the coils are stationary, no current is induced. But when the small coil is moved in or out of the large coil(B), the magnetic flux through the large coil changes, inducinga current which is detected by the galvanometer

Answer 2

Faraday's first law of electrolysis gives a relation between the amount of mass deposited or eroded at an electrode with the charge passing through the electrolytic cell. It is verified by a simple experiment involving a battery, electrolytic cell, ammeter, resistor and key.
