What is the working principle of galvanometer?

When an electric current passes through the coil, it generates a magnetic field that interacts with the field of the permanent magnet. This interaction produces a torque on the coil, causing it to rotate. The rotation moves the attached pointer across the scale, allowing the current to be measured. The amount of rotation (and thus the pointer deflection) is proportional to the current passing through the coil.
