The main uses of helmholtz coil measurement system

        A Helmholtz coil is a coil combination consisting of one or more pairs of coils with the same number of turns, the same winding method, and a coil radius equal to the coil spacing.

        According to the shape of the coil, the helmholtz coil can be divided into circular helmholtz coil and square Helmholtz coil. According to the direction of magnetic field, helmholtz coil can be divided into one-dimensional helmholtz coil, two-dimensional Helmholtz coil and three-dimensional Helmholtz coil. Helmholtz coil can be divided into DC helmholtz coil and AC Helmholtz coil according to coil current properties.

        Helmholtz coil, uniform area of large volume, open space, easy to operate, with it can produce a very weak magnetic field to hundreds of gauss magnetic field; Can realize one-dimensional, two-dimensional, three-dimensional combined magnetic field, can provide the coil current proportional to the AC magnetic field or DC magnetic field; Its internal space can be fitted with a suitable non-magnetic support platform, which is convenient for users to place the measured instruments or experimental equipment. It is very suitable for various research institutes, universities and enterprises to do material magnetic or detection experiments, and applied to various disciplines such as materials, electronics, biology, medical treatment, aerospace, chemistry, applied physics and so on.

Helmholtz coil main uses:
