Problems solved by technology

This conventional momentless magnetic field coil has the advantage of simple structure, but it only has an opening space in the axial direction, which cannot meet the radial test requirements
If a Helmholtz-type momentless coil is used, although it can meet the requirements of axial and radial openings at the same time, at least 4 rings are required to form a momentless magnetic field coil, which increases the difficulty of the structure, especially when small-sized momentless coils are required. In the case of a coil

Embodiment 1

[0021] Embodiment 1. The skeleton of the magnetic field coil is composed of two coaxial solenoids with unequal radii. On each solenoid, there are two pairs of windings symmetrically distributed along the central axis along the central axis. Each pair of windings includes The two windings are a pair of windings on the same side of the central axis, and there is a gap between the two windings; the gaps between the two windings on both sides of the central axis are used for radial openings.

[0022] The central magnetic axes of the inner and outer solenoids coincide, and the inner and outer solenoids are connected in reverse series.

[0023] The dimensions of the two solenoids, the windings such as figure 1 shown, on the same side of the central axis, with R 1 , R 2 is the effective radius of the inner and outer solenoids after winding; L 1,1 , L 1,2 , L 1,3 , L 1,4 Respectively, the distance between a pair of winding edges of the inner solenoid on this side and the central...

Abstract

The invention discloses a non-moment solenoidal magnetic field coil with radial openings. The magnetic field coil is formed by combining an inner solenoid with an outer solenoid; two pairs of windings are distributed on each solenoid in a bilateral symmetry manner by taking a central section as an axis; each pair of windings include two winding sections; a gap is formed between the two winding sections of one pair of windings on the same side of the axis; the gap between the two winding sections on two sides of the axis is provided with the radial openings; central magnetic axes of the inner and outer solenoids coincide; the inner and outer solenoids are reversely connected in series; and certain relations of the winding intervals and the radiuses of the two solenoids, certain relations of the numbers of turns and the intervals of coil windings, and certain relations of the numbers of turns of coil windings and the radiuses of the solenoids are satisfied, so that radial test demands of the non-moment coil are met.

Description

technical field [0001] The invention relates to the magnetic field coil technology, in particular to a radial opening torqueless solenoid magnetic field coil technology. Background technique [0002] In the fields of magnetic measurement, atomic optics, etc., it is often necessary to use moment-free magnetic field coils with radial openings in order to perform testing work both axially and radially. Conventional moment-free magnetic field coils generally use a combination of two solenoidal magnetic field coils that are coaxial but have unequal radii. This conventional momentless magnetic field coil has the advantage of simple structure, but it only has an opening space in the axial direction, which cannot meet the radial test requirements. If a Helmholtz-type momentless coil is used, although it can meet the requirements of axial and radial openings at the same time, at least four rings are required to form a momentless magnetic field coil, which increases the difficulty of...
