Please answer my question guys It's very much important

According to Fleming's left Hand rule , when a current is passed through a coil a conductor is brought around it a sudden Deflection is Seen in The Galvanometer .The type of Deflection differs depending upon the director in which the current flow And after a certain time the needle of the Galvanometer will come to the initial position .This is because of Magnetic Effect of Electric Current
Answer:
According to the question, we can see that the current in the first coil changes, the magnetic field associated with it also changes.
Therefore, the magnetic field lines around the other coil also change.
Because of it, a momentary deflection in galvanomerer will be observed which will end out soon.
Now, because of to similar conclusion, a momentary deflection is again observed in opposite direction when key is removed.
