When a bar magnet is pushed into or pulled out of a solenoid connected to a galvanometer, the magnetic field within the solenoid changes. This change in magnetic field induces an electromotive force (EMF) in the solenoid, which in turn generates an electric current. This electric current flows through the galvanometer, causing the needle to deflect.
If the bar magnet is pushed into the solenoid, the direction of the induced current will be one way, causing the galvanometer needle to deflect in one direction. If the bar magnet is pulled out of the solenoid, the direction of the induced current will be the opposite way, causing the galvanometer needle to deflect in the opposite direction.
Overall, pushing a bar magnet into or pulling it out of a solenoid connected to a galvanometer will result in a change in the magnetic field, inducing an electric current and causing the galvanometer needle to deflect.

When a Bar Magnet is Pushed into a Solenoid:
- Current Induction: The movement of the magnet causes a change in the magnetic flux through the solenoid, which induces an electromotive force (EMF) in the solenoid.
- Galvanometer Response: The EMF generated in the solenoid causes a current to flow through the galvanometer, resulting in a deflection of the galvanometer pointer.
- Polarity of Current: The direction of the current depends on the direction of movement of the magnet. If the magnet is pushed into the solenoid, the current flows in one direction, and if it is pulled out, the current flows in the opposite direction.
- Magnitude of Deflection: The magnitude of the galvanometer deflection is proportional to the rate of change of magnetic flux through the solenoid.
When a Bar Magnet is Pulled Out of a Solenoid:
- Current Induction: The same as when the magnet is pushed into the solenoid.
- Galvanometer Response: The galvanometer pointer deflects in the opposite direction compared to when the magnet is pushed in.
- Polarity of Current: The direction of the current reverses compared to when the magnet is pushed in.
- Magnitude of Deflection: The magnitude of the galvanometer deflection is again proportional to the rate of change of magnetic flux through the solenoid.
Additional Observations:
- The galvanometer deflection will be zero if the bar magnet is moved very slowly, as the change in magnetic flux is negligible.
- The deflection will be maximum if the bar magnet is moved rapidly, maximizing the rate of change of magnetic flux.
- The direction of the galvanometer deflection can be used to determine the direction of movement of the bar magnet.
