Measurement method of magnetic field spatial distribution based on plane measuring ring

摘要

In this paper, it is presented that a spatial magnetic field measurement system for space magnetic field single dimension measurement and multi plane magnetic field synthesis. The system consists of a cylindrical electromagnetic field, a spatial device, a plane measuring ring, and a measuring circuit set. The cylindrical electromagnetic field spatial device is a hollow cylindrical structure. A plane measuring ring is arranged on the inner wall of the cylinder along the vertical cylinder wall, and the measuring ring can move up and down along the inner wall. A measuring rod with a ruler is arranged in the direction of the diameter of the measuring ring, and the measuring rod can rotate around the center of the measuring ring. A measuring circuit group is provided at intervals between the measuring rods. Used to obtain three one-dimensional magnetic field data in each direction of each measurement point covered by the measuring ring and then three dimensional magnetic field data are obtained. The measured data are analyzed, processed, and synthesized to form a magnetic field in which the measuring ring is located. The horizontal position of the measuring ring is adjusted, and the magnetic field of different planes is obtained. Finally, the distribution of the magnetic field is obtained. This method lays a solid foundation for further study of the spatial constant magnetic field and the fast pulsating magnetic field distribution.
