Question

State faradays law of induction

Answer 1

states that the magnitude of the emf induced in a circuit is proportional to the rate of change of the magnetic flux that cuts across the circuit.

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.
