Tangent Galvanometer
Product Code : EL-LM-10393
The Tangent Galvanometer from Lab Exports is an early measuring instrument for small electric currents, based on the tangent law of magnetism, which states that a current passed through a circular coil produces a magnetic field at the coil's center perpendicular to its plane. The copper wire consists of three windings (2, 50 and 500 turns) with 4 terminals for coil connection, mounted on a non-magnetic tripod metal base with leveling screws, and the coil can be rotated on a vertical axis through its centre. The instrument comprises an insulated copper coil wound on a non-magnetic Bakelite bobbin about 162.5 mm in diameter, an aluminium dial 100 mm in diameter graduated 0–90° four times, an anti-parallax mirror, and an agate-centered magnetic needle. Lab Exports manufactures and exports this galvanometer from India to schools, colleges and laboratories worldwide.
