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
The correct answer is: B
Explanation
Sensitivity of a galvanometer increases when number of turns, area of coil and magnetic field increase
