The sensitivity of the galvanometer can be increased by increasing the:
Correct answer: D. All of these
- A. Area of the coil
- B. Strength of magnetic field
- C. Number of turns of the coil
- D. All of these
Explanation
All of these: Therefore, all of the options (increasing the area of the coil, the strength of the magnetic field, and the number of turns of the coil) contribute to increasing the sensitivity of the galvanometer. By optimising these factors, the sensitivity of the galvanometer can be maximised, allowing it to detect even small currents with greater precision.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
