Two coils C1 and C2 are wrapped around a non conducting cylinder. Coil C1 is
connected to a battery and key and C2 with galvanometer G. On pressing thekey (K), current starts flowing in the coil C1. State your observation in thegalvanometer :(i) When key K is pressed on.(ii) When current in the coil C1 is switched off.(iii) When the current is passed continuously through coil C1.(iv) Name and state the phenomenon responsible for the above observation.Write the name of the rule that is used to determine the direction of currentproduced in the phenomena.

Explanation:
(i) When key is pressed on, the galvanometer needle deflects momentarily in one direction
(ii) When the current in the coil C1 is switched off, the galvanometer needle deflects again momentarily but in opposite direction to that in the previous case.
(iii) When current is passed continuously through coil C1, no deflection is observed in the galvanometer.
(iv) The phenomenon responsible for the above observations is electromagnetic induction.
Electromagnetic Induction: The process, by which a changing magnetic field in a conductor induces a current in another conductor placed nearby, is called electromagnetic induction.
• Fleming’s right hand rule is used to determine the direction of current produced in the phenomena of electromagnetic induction.

Answer:
The correct answer of this question is Electromagnetic induction refers to the mechanism by which a changing magnetic field in one conductor generates a current in another neighboring conductor.
Explanation:
Given - Two coils C1 and C2 are wrapped around a non conducting cylinder.
To Find - Name and state the phenomenon responsible for the observations .
Electromagnetic Induction - Electromagnetic induction refers to the mechanism by which a changing magnetic field in one conductor generates a current in another neighboring conductor. • Fleming's right hand rule is used to determine the direction of current created in electromagnetic induction processes.
(i) When a key is pressed, the galvanometer needle deflects in one direction for a brief duration.
(ii) When the current in coil C1 is turned off, the galvanometer needle deflects briefly again, but in the opposite direction as in the prior case.
(iii) When current is continually passed via coil C1, no deflection in the galvanometer is detected.
(iv) Electromagnetic induction is the phenomena responsible for the observations made above.
