Question

Observe the following phenomenon shown in the following picture. 
a)      Why the galvanometer gets deflected as the bar magnet is brought near to the loop of wire?
b)What will happen if the magnet is taken away from the loop of wire?     
PLEASE ANSWER​

Answer 1

This involves generating a voltage by changing the magnetic field that passes through a coil of wire. ... 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.
