Tangent Galvanometer (Aluminum) Tangent Galvanometer (Aluminum) – Physics Laboratory Instruments A tangent galvanometer is an early measuring instrument used for the measurement of electric current. It works by using a compass needle to compare a magnetic field generated by the unknown current to the magnetic field of the Earth. The magnetic needle is free to rotate in the horizontal plane. Feature – Having three standard windings 2, 5, 50 or 2, 50, 500. The bakelite ring with winding is mounted in bakelite base. The whole assembly rotates on a nonmagnetic tripod base. With nonmagnetic leveling screw. Complete with compass box.
