Embodiment Construction

[0020] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0021] Such as figure 1 As shown, the device for measuring the two-pole magnetic moment of a space magnet of the present invention includes a space magnet 1, a support rod 2, a rotating frame 3, a boom 4, a Helmtz coil 5, a support base 6, a force gauge 7, and Fixing frame 8. Place the space magnet 1 on the support base 6, place the support rod 2 above the space magnet 1, and install the rotating frame 3 on the support rod 2. The rotating frame 3 hangs two Helmz coils 5 on the suspension rod 4 through the suspension rod 4 One of the Helmtz coils 5 is connected to one end of the dynamometer 7, and the other end of the dynamometer 7 is fixed by a fixing frame 8. As the magnetic field generated by the Helmtz coil 5 interacts with the magnetic moment of the space magnet 1, a rotational moment is generated. The Helmz coil 5 is subjected to a rotating moment, and ...

Abstract

The invention relates to a device for measuring ambipolar magnetic moment of a spatial magnet, which comprises the spatial magnet (1), a supporting rod (2), a rotary rack (3), a suspender (4), a Helmholtz coil (5), a supporting seat (6), a dynamometer (7) and a fixed bracket (8). A magnetic field produced by the Helmholtz coil (5) interacts with the magnetic moment of the spatial magnet (1) so asto produce a rotary moment; and the Helmholtz coil (5) rotates on the supporting rod (2) supported by the supporting seat (6) under the action of the rotary moment through the rotary rack (3) and thesuspender (4). The ambipolar magnetic moment of the spatial magnet is measured by measuring the rotary moment of the Helmholtz coil (5).

Description

Technical field [0001] The invention relates to a measuring device and a measuring method for the two-pole magnetic moment of a magnet, in particular to a measuring device and a measuring method for the two-pole magnetic moment of a large space magnet. Background technique [0002] In space exploration technology, superconducting or permanent magnets with higher magnetic fields are usually used. The measurement and compensation technology of the two-pole magnetic moment of a large permanent magnet for space antimatter detection also has important application significance for other space magnets. The scientific mission of space magnetic exploration is to find antimatter and dark matter in the universe, and to accurately measure the relative abundance of various isotopes and high-energy gamma photons in the universe. Magnetic spectrometer is a key equipment for particle physics and nuclear physics research. It can measure the deflection of charged particles in a magnetic field and...
