Helmholtz Tangent Galvanometer. It consist of two parallel co-axial coils C1 and C2 having the same radius (a) and the same number of turns (N). The distance. Helmholtz Galvanometer it consists of two equal coaxial coils parallel to each other separated by a distance equal to the radius of the coils. These are made by . They are the measuring sensors as they carry current in them for any flux variation.

Image Unavailable Image not available for Color: Each coil carries an equal electric current in the same direction. From Wikipedia, the free encyclopedia. In other projects Wikimedia Commons. By passing current in one direction and then in reverse direction and then taking the mean of the helmboltz readings.
The coils are inductors, and their impedance increases proportionally with frequency.

This is sometimes called a Maxwell coil. Many applications and experiments require a time-varying magnetic field.

Instead of directly driving the coil with a high voltage, a series resonant circuit may be used to provide the high voltage. By using two identical coils placed co-axially at a galvanomfter equal to their radius. What is the magnitude of of field at the center?
