Question

what is electromagnetic induction write the Faraday's law of electromagnetic induction

Answer 1

whenever a coil is rotated inside a magnetic field lines it breaks the magnetic field lines of the magnet and the direction of magnetic field lines change and the current is induced. this process of inducing the current is called electromagnetic induction

hope you understand
please like and comment

Answer 2

The phenomenon of producing an electric current in a conductor due to changes in the magnetic lines of force associated with the conductor is called electromagnetic induction.
FARADAY'S LAW OF MAGNETIC INDUCTION :-
• When the magnet is stationery and kept outside the coil , the needle of the galvanometer does not deflect and the reading of the galvanometer is zero
• when the magnet moved towards the coil, the galvanometer needle shows deflection . This shows the presence of current in the coil.
• When the magnet is completely inside the coil but not moving the galvanometer reading again come to zero . This shows the absence of flow of electric current in the coil
• when the magnet is being moved away from the coil, the galvanometer needle again shows deflection but in opposite direction .

Hope it helps !!!!!!
