5311474 Illustration depicting a Galvanometer showing magnet and rotating coil.
A galvanometer is an electromechanical instrument used for detecting and indicating electric current. Galvanometers developed from the observation that the needle of a magnetic compass is deflected near a wire that has electric current flowing through it, first described by Hans Oersted in 1820. They were the first instruments used to detect and measure small amounts of electric currents.; (add.info.: Date: 1887); Universal History Archive/UIG
