प्रश्न
Write the underlying principle of a moving coil galvanometer.
State the principle of working of a galvanometer
उत्तर
Principle:
- When a current-carrying coil is placed in a magnetic field, it experiences torque. This is the underlying principle of a moving coil galvanometer.
- This torque tends to twist the coil about the suspension axis, increasing the magnetic flux going through the coil.
