Q. How can we increase the current sensitivity of a galvanometer?

The current sensitivity of a galvanometer is able to be increased by

(i) Rising the number of turns

(ii) Rising the magnetic induction

(iii) Rising the area of the coil

(iv) Declining the couple per unit twist of the suspension wire.
