The Tangent Galvanometer is a precision laboratory instrument used to measure small electric currents and to study the relationship between electric current and magnetic fields. It is widely used in school, college, and university physics laboratories for experiments involving the tangent law of magnetism and the horizontal component of the Earth's magnetic field.
The apparatus consists of a circular coil mounted vertically on a non-magnetic base with a highly sensitive magnetic compass positioned at the center. When an electric current passes through the coil, it produces a magnetic field that causes the compass needle to deflect. The current is determined by measuring the angle of deflection using the tangent law, making the instrument ideal for practical demonstrations and educational experiments.
Manufactured from high-quality materials, the Tangent Galvanometer ensures accurate measurements, excellent stability, and long-lasting performance. It is an essential instrument for teaching electromagnetism and developing practical laboratory skills in physics.
