The reason for having a large number of turns in the coil of a moving coil galvanometer is to--------
make the deflection of the needle proportional to the current
increase the sensitivity of the galvanometer
decrease the magnetic flux produced by the magnet
make the permanent magnet stronger
Selitys
Sensitivity of a galvanometer increases when number of turns, area of coil and magnetic field increase
