The force which deflects the coil of the galvanometer is called:
Correct answer: A. Deflecting torque
- A. Deflecting torque
- B. Ordinary torque
- C. Reflecting torque
- D. None of these
Explanation
In a galvanometer, the coil is suspended within a magnetic field and carries the current to be measured. When a current flows through the coil, it experiences a torque due to the interaction between the magnetic field and the current-carrying coil. This torque causes the coil to rotate, deflecting it from its original position. This torque is referred to as the deflecting torque because it is responsible for deflecting the coil, which is the fundamental operation of a galvanometer.

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.
