About This Product
A tangent galvanometer is a coil with a small compass needle at its centre. The coil is turned until its plane lies along the magnetic meridian, and a current is passed through it. The needle then turns through an angle, and the tangent of that angle is proportional to the current, which is the tangent law. Students use it to compare currents and to find the reduction factor and the horizontal component of the Earth's magnetic field. Alongside supply within India, the Tangent Galvanometer for Physics Lab is offered for export to Tunisia, Zimbabwe, Fiji, Nicaragua, Libya and Gambia.
Frequently Asked Questions
Q1. How many windings does the Tangent Galvanometer have?
It has three windings of 2, 50 and 500 turns on a bakelite ring or bobbin of 165 mm diameter.
Q2. What does the compass box include?
A bakelite base with a metal dial of 100 mm diameter, graduated in degrees, with an anti-parallax mirror.
Q3. How is the needle mounted?
A cobalt steel magnet and aluminium pointer are mounted on synthetic sapphire and move on a special pivot, which makes the needle virtually frictionless.
