Helmholtz coilIt consists of a pair of identical circular conductor coils. Using a Cartesian coordinate system, the central axes of both circular coils of radius R are coaxial with the z-axis. The z-coordinates of the two circular coils are
with
. Each conductor coil carries a current I in the same direction.
Helmholtz coilThe range of applications includes eliminating the geomagnetic field, generating magnetic fields for experiments, and applications that require such fields. The generated Helmholtz magnetic field can be a static magnetic field, a time-varying DC magnetic field, or an AC magnetic field, depending on the field of application. In some applications, Helmholtz coils can be used to counteract the geomagnetic field, creating a region of near zero magnetic field.
With two coils with exactly the same radius and number of turns, arrange them coaxially and make the spacing equal to the radius. This coil combination is calledHelmholtz coil. It can be used to generate a very weak magnetic field up to hundreds of Gs magnetic field; the coil, the uniform area of large volume, the use of open space, easy to operate. Can achieve one-dimensional, two-dimensional, three-dimensional combination of magnetic field, can provide AC and DC magnetic field, current and magnetic field has a good linear relationship. It is suitable for various research institutes, universities and enterprises to do material magnetism or detection experiments, and is applied to various disciplines such as materials, electronics, biology, medical treatment, aerospace, chemistry, applied physics, etc. Its main purpose: to produce standard magnetic field; the offset and compensation of the earth's magnetic field, the simulation of the geomagnetic environment, the determination of magnetic shielding effect, the simulation experiment of electromagnetic interference, the calibration of Hall probe and various magnetometers, the study of biological magnetic field and the study of the magnetic characteristics of substances.
