Notes on faraday's law of electromagnetic induction

Answer 1

FIRST LAW. First Law of Faraday's Electromagnetic Induction state that whenever a conductor are placed in a varying magnetic field emf are induced which is called induced emf, if the conductor circuit are closed current are also induced which is called induced current.

Answer 2

Answer:Faraday's Law of Electromagnetic Induction :

A change in the magnetic environment of the coil or conductor will cause a voltage(emf) induce in the coil. Faraday law is the fundamental relationship which comes from the Maxwell’s equation.

◇ Faraday's First Law : A conductor is induced with an electromotive force when the surrounding magnetic field changes.

◇ Faraday's 2nd Law : The rate of change of field is directly proportional to the magnitude of the electromotive force.

◇ Faraday's 3rd Law : The sense of the induced electromotive force depends on the direction of the rate of the change of the field.

E= – ndǿ/ dt.

In this the induced emf (e) and the change in magnetic flux (d) have opposite signs.
