Definition: The Galvanometric method, also known as the galvanometer principle, is a device used to measure electric current. It consists of a wire carrying an electric current and a small metal rod that can be moved along the wire. When the rod is moved along the wire, it creates a magnetic field around the wire. This magnetic field deflects a magnet placed near the rod, which can then be read out by a device such as a galvanometer. Galvanometric methods are used in
