Question

Coils.When connected to key whch is plugged in then how the galvanometer reading change

Answer 1

Answer:

Explanation:

The galvanometer deflects left/right depending on the change in magnetic flux linkage. The galvanometer will only deflect when there’s a change in magnetic flux linkage (Faraday’s Law). If the solenoid is stationary, the galvanometer will not deflect when there’s no cutting of magnetic field.
