State the principle of working of a galvanometer

Short/Brief Note

Solution

Principle:

  1. When a current-carrying coil is placed in a magnetic field, it experiences torque. This is the underlying principle of a moving coil galvanometer.
  2. This torque tends to twist the coil about the suspension axis, increasing the magnetic flux going through the coil.
