Web72.48 -- Mutual induction with coils and galvanometer. A video of this demonstration is available at this link. The power supply is connected to the coil at left through a tap switch. The coil at right is connected to a galvanometer. When you depress the switch, the galvanometer needle rapidly deflects to one side and immediately swings back to ... WebThe galvanometer’s primary function is to determine the presence, direction, and strength of an electric current in a conductor. This is based on the principle of energy conversion …
Web13 Apr 2024 · Galvanometers can be divided into two types: Moving coil galvanometers: the most common type. In this type of instrument, the needle is connected to a coil by means of a spring, and a fixed magnet generates the magnetic field that makes the coil move. As the electrical current travels, it moves the needle proportionally to the current’s strength.
