A galvanometer is an electromechanical instrument used for detecting and indicating
electric current . A galvanometer works as an
actuator , by producing a rotary deflection (of a "pointer"), in response to electric current flowing through a coil in a constant magnetic field . Early galvanometers were not calibrated, but their later developments were used as measuring instruments, called ammeters , to measure the current flowing through an electric circuit.
