Q.) State the Faraday's Law of electromagnetic induction.
Answers
Whenever the number of magnetic lines of force passing through a coil changes,current is induced in the coil....
This is known as Faraday's law of electromagnetic induction.....
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.
