For the voltage of any circuit,
It is a common fact that when current flows the circuit, connected with a magnetic compass, the magnetic needle in the compass will show deflection due to the magnetic effect of the current.

Magnetic lines of forces are created around the coil of wire and this caused the needle to deflect according to the direction of the current.

In this case, when the number of turn of the coil around the magnetic compass is increased, the current through the circuit is also increased. This is because, the increase in current through the circuit is directly proportional to increase in the number of turns in the coil

Hence, as the current increases in the circuit, the deflection in the magnetic needle also increases.
