Abstract

The invention relates to the technology of compensating space magnetic field, in particular to a device capable of compensating uniform magnetic field and gradient magnetic field at the same time. The invention solves the problem that the Helmholtz compensation magnetic field coil widely used at the present stage cannot compensate the non-zero gradient magnetic field when eliminating the residual uniform magnetic field in space. The method and device for simultaneously compensating the residual uniform magnetic field and the gradient magnetic field in space include: a current loop formed by series connection of a power supply, a compensation coil, a sampling resistor and a field effect tube in sequence, and a feedback circuit for realizing independent control of the current of each compensation coil. The invention is suitable for precision measurement, product calibration and cold atom science experiment which are seriously affected by spatial residual uniform magnetic field and gradient magnetic field.

Description

technical field [0001] The invention relates to the technical field of magnetic field compensation, in particular to a device for simultaneously compensating a spatial residual uniform magnetic field and a gradient magnetic field. Background technique [0002] Any point in the earth's near-earth space has a geomagnetic field, that is, the magnetic field distributed in space around the earth, and its strength and direction will vary with different latitudes and longitudes and altitudes. In addition, weakly magnetic metal devices and energized equipment will also generate stray magnetic fields around them, which vary with spatial positions. These magnetic fields can be regarded as spatial residual magnetic fields, which have caused huge interference to the frequency standards provided by atomic interferometers, the calibration of precision measurement products, and the research and development of new materials. In order to compensate the residual magnetic field in a certain d...
