Which one of the following modifications may increase the sensitivity of moving coil galvanometer?
1st way: By using weaker hair springs
2nd way: By using a smaller coil
3rd way: By using a coil having fewer no. of turns
4th way: by using a strong magnet

Use
current sensitivity=NBA/K
here:
K is torsional constant
current sensitivity=NBA/K
