- Increase the turns on the coil. - Increase the electromagnetic field strength that produces the torque on the movement, deflecting the pointer.
- Use a more powerful magnet. - Increases the magnetic field strength allowing more torque on the movement.
- Use a smaller taut band or hair spring.

Hello!!
The sensitivity of the galvanometer can be increased either by increasing the number of turns using strong magnet or increasing the area of the coil. Sensitivity of a moving coil galvanometer is defined as the current in microampere required to consume 1 millideflection.
Thanks
