Question

why galvanometer deflects when bar magnet is kept inside and outside of solenoid.​

Answer 1

Answer:

There is no battery or power supply, so no current should flow. ... If the magnet is held stationary near, or even inside, the coil, no current will flow through the coil. If the magnet is moved, the galvanometer needle will deflect, showing that current is flowing through the coil.
