The working principle of galvanometer is based upon:
Correct answer: B. Torque
- A. Momentum
- B. Torque
- C. Force
- D. Impulse
Explanation
The working principle of a galvanometer is indeed based on the torque that acts on a current-carrying coil placed within a magnetic field. This torque causes the coil to rotate, and the angle of rotation is proportional to the current flowing through the coil, allowing for its measurement.

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.
