(Summary description)The Helmholtz coil is composed of a pair of identical circular conductor coils. Using a rectangular coordinate system, the central axes of the two circular coils with a radius of R are coaxial with the z-axis. The z-coordinates of the two circular coils are and respectively, and each conductor coil carries a current I in the same direction.

The Helmholtz coil has a large average area, a wide application space, and cumbersome operation. It can complete one-dimensional, two-dimensional, and three-dimensional combined magnetic fields, and can provide AC and DC magnetic fields. The current has a good linear relationship with the magnetic field. It is suitable for various research institutes, universities and enterprises to do material magnetism or testing experiments. It is applied to various disciplines such as information, electronics, biology, medical treatment, aerospace, chemistry, applied physics, etc. Its main use: to generate a standardized magnetic field; Cancellation and compensation, geomagnetic environment simulation, determination of magnetic shielding effect, electromagnetic interference simulation experiment, calibration of Hall probes and various magnetometers, research on biological magnetic field and research on magnetic properties of materials.
