Question

Faraday's first law

Answer 1

Faraday’s First Law:

Faraday’s First Law of Electromagnetic Induction states that whenever a conductor is placed in varying magnetic field emf are induced which is known as induced emf if the conductor circuit is closed current are also induced which are called induced current.

Ways of changing magnetic field:

1. By rotating the coil relative to the magnet.
2. By moving the coil into or out of the magnetic field.
3. By changing the area of a coil placed in the magnetic field.
4. By moving a magnet towards or away from the coil.
