A galvanometer is made sensitive by:
Correct answer: C. Increasing the magnetic field
- A. using a small and thick suspension wire
- B. decreasing the area of the coil
- C. Increasing the magnetic field
- D. reducing the number of turns of the coil
Explanation
The formula for the current sensitivity of a galvanometer is given by: I=cθ/ NAB So, it can enhance the galvanometer's ability to detect smaller currents by increasing its current sensitivity, which is the deflection per unit current produced by the galvanometer.

About Magnetic Flux Density
Magnetic flux density measures the magnetic force acting on a current carrying conductor or moving charge in a magnetic field. Work includes the relations B equals F divided by IL and F equals qvB, the tesla as its SI unit, field direction and the distinction between flux density and magnetic flux.
