MCQ
The restoring couple in the moving coil galvanometer is due to:
- ACurrent in the coil
- BMagnetic field of the magnet.
- CMaterial of the coil.
- ✓Twist produced in the suspension wire.
✓
Answer
Correct option: D.
Twist produced in the suspension wire.
When coil rotates the spring is twisted and it exerts an opposing torque on the coil.
