Answer:
Electromagnetic induction is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field. the other coil-2 is connected with a galvanometer as shown.
We will observe that the needle of the galvanometer instantly jumps to one side and then quickly returns to zero, indicating a momentary current in coil-2.
The coil-1 is now disconnected from the battery. Now we will observe that the needle momentarily moves, but to the opposite side. It means that now the current flows in the opposite direction in coil-2.
