The current sensitivity of a Galvanometer can be increased by increasing the magnetic induction.The current sensitivity of a galvanometer is defined as the deflection produced in the galvanometer when a unit current passes through it. The current sensitivity of a galvanometer can be increased by:
1) Increasing the number of turns.
2) Increasing the magnetic induction.
3) Increasing the area of the coil.
4) Decreasing the couple per unit twist of the wire.
