Tangent Galvanometer
Product Code : JA-PLE-4130
The Tangent Galvanometer (SKU JA-PLE-4130) is a moving-magnet instrument in which a compass needle at the centre of a vertical circular coil is deflected by the current in the coil according to the tangent law. This tangent galvanometer with 2, 50 and 500 turns is used in college and B.Sc physics practicals on the magnetic effect of current, and JaincoLab manufactures it in Ambala, India.
Specifications
The tangent galvanometer has a 165 mm bakelite ring carrying three windings of 2, 50 and 500 turns, and a compass box with a 100 mm metal dial graduated in degrees, an anti-parallax mirror and a needle mounted on synthetic sapphire.

Applications of the tangent galvanometer in physics practicals
The tangent galvanometer is set with its coil in the magnetic meridian; a current through one of the windings deflects the needle, and the tangent of the deflection is proportional to the current, which lets students relate current, number of turns and the earth’s magnetic field.
- Determining the horizontal component of the earth’s magnetic field
- Verifying the tangent law of magnetism
- Finding the reduction factor of the galvanometer for each winding
- Comparing deflections for the 2, 50 and 500 turn windings at the same current
- B.Sc and engineering physics practicals on the magnetic effect of current
