Which of the following works on torque on the current-carrying conductor placed in a magnetic field?
Correct answer: A. galvanometer
- A. galvanometer
- B. ammeter
- C. voltmeter
- D. all of the above
Explanation
A galvanometer is an instrument that measures electric current, and it works on the principle of the torque experienced by a current-carrying coil in a magnetic field. The torque causes the coil to rotate, and this rotation is proportional to the current passing through it.

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.
