The coil of a moving coil galvanometer is wound over a metallic frame
- A to increase moment of inertia
- B to provide electromagnetic damping
- C to increase its sensitivity
- D to reduce hysteresis loss
Answer & Solution
Correct Answer
(B) to provide electromagnetic damping
Step-by-step Solution
Detailed explanation
When the coil moves, eddy currents are induced in the metallic frame which produce a magnetic force that opposes the motion. This electromagnetic damping ensures the pointer comes to rest quickly at its equilibrium position instead of oscillating back and forth. B) to provide…
