Explanation:
1- When the bar magnet is pushed into the coil the momentary deflection is observed in the galvanometer. This deflection indicates that momentary current is produced in the coil
2- In pulling the magnet out of the coil, the deflection is indicated in the opposite direction.It indicates the current in the coil is in opposite direction
3- Electromagnetic induction
