What is a Galvanometer used for

An electromechanical device used to detect and show an electric current is a galvanometer. A galvanometer acts as an actuator in response to electrical current flowing through a coil in a continuous magnetic field by generating a rotary deflection of a pointer.

A galvanometer is a device (instrument) used in a circuit to detect weak electrical voltages and currents. It has a coil of a solid laminated horse shoe magnet pivoted (or suspended) between concave pole faces. It deflects as an electrical current travels through the coil.
