Explain Faraday's law of induction with the help of activity.
i. Whenever there is the continuous change in the magnetic flux linked with the closed coil the current is generated in the coil.
ii. The current generated is called the induced current and the phenomenon is called as the Electromagnetic Induction.
Activity To Demonstrate Faraday’s Law: Connect the terminals of the coil to the sensitive galvanometer (Galvanometer is a device used to detect the current in the circuit ) as shown in the figure.
Initially we will not see any deflection in the needle of the Galvanometer because there is no current in the circuit.
Bring the Bar Magnet near the coil and move it towards the coil and away from the coil.
● When the bar magnet is move towards the coil with its north pole facing the coil The needle of the galvanometer gets deflected.
● The needle does not gets deflected when the bar magnet is at rest
● When the bar magnet is moved away from the coil the needle gets deflected in the opposite direction.
Result and Explanation:
On Moving the Bar magnet towards the coil and away from the coil the magnetic flux( The magnetic field lines) passing through the coil changes and this change of flux induces the current in the coil. This is the faraday’s law.
