The reason for having a large number of turns in the coil of a moving coil galvanometer is to?

A. make the deflection of the needle proportional to the current
B. increase the sensitivity of the galvanometer
C. decrease the magnetic flux produced by the magnet
D. make the permanent magnet stronger

Correct Answer:

Option B = increase the sensitivity of the galvanometer

Explanation

Sensitivity of a galvanometer increases when number of turns, area of coil and magnetic field increase
