Helmholtz Galvanometer

Description

It consists of two equal coaxial coils (parallel to each other) separated by a distance equal to the radius of the coils. The permanent magnetic compass is

pivoted on the brass cup in the midway between them and in the same direction. The coils increase the uniformity of the fields in the middle and thus make it more

sensitive. Supplied with a superior quality permanent Magnetic Compass box.
