tangent galvanometer

noun

1. a type of galvanometer having a vertical coil of wire with a horizontal magnetic needle at its centre. The current to be measured is passed through the coil and produces a proportional magnetic field which deflects the needle

Two fixed circular coils are placed apart at a distance equal to the radius of either coil, so that a current passing through them creates in the central Tangent galvanometer. region between them a nearly uniform magnetic field.

From Project Gutenberg

In 1849 H. von Helmholtz devised a tangent galvanometer with two coils.

From Project Gutenberg

A continuous current ammeter, for instance, can be calibrated, so far as the relative values of its readings are concerned, by comparison with a tangent galvanometer, since it is known that the current in this instrument is proportional to the tangent of the angle of deflection.

From Project Gutenberg

A tangent galvanometer, or a needle-telegraph instrument, for example, may be connected with Y and Z. 227.
