Explanation:

When a bar magnet is pushed towards the coil connected in series with a galvanometer, the pointer in the galvanometer shows deflection while the bar is in motion. This deflection occurs due to electromagnetic induction.

1. Electromagnetic Induction:
- When a magnet is moved towards a coil, a change in magnetic field is produced.
- This change in magnetic field induces an electromotive force (emf) in the coil.
- According to Faraday's law of electromagnetic induction, the induced emf produces an electric current in the coil.

2. Galvanometer:
- A galvanometer is a device that detects the presence and direction of electric current.
- It consists of a coil suspended between the poles of a permanent magnet.
- When an electric current flows through the coil, it experiences a magnetic field and gets deflected.

3. Pushing the Bar Magnet:
- When the bar magnet is pushed towards the coil, a change in magnetic field occurs.
- This change induces an emf in the coil.
- The induced emf produces an electric current in the coil.

4. Deflection of the Galvanometer:
- The electric current flowing through the coil causes a magnetic field.
- This magnetic field interacts with the magnetic field of the permanent magnet.
- As a result, the coil experiences a force and gets deflected.
- The deflection of the coil is indicated by the pointer in the galvanometer.

5. Continuous Deflection:
- As long as the bar magnet is in motion towards the coil, the magnetic field and induced emf keep changing.
- This results in a continuous deflection of the galvanometer pointer.
- The deflection stops when the bar magnet reaches a stationary position or is moved away from the coil.

In conclusion, when a bar magnet is pushed towards the coil connected in series with a galvanometer, the pointer in the galvanometer shows deflection while the bar is in motion. This deflection occurs due to the electromagnetic induction and the interaction between the magnetic fields of the coil and the permanent magnet.
