Q.3. (A) Explain the given statement.
The faster the displacement of the solenoid, the larger is the deflection of the galvanometer.
Ans.​

Answer 1

induced current (produced when there's a change in magnetic field) is directly proportional to the speed in movement of the solenoid.

so, when the speed in movement of solenoid increases, the induced current generated also increases and thus we can observe a larger deflection in the galvanometer.
