Abstract Under pressure, the magnetic field outside the ferromagnetic cavity is more complex under the influence of the background magnetic field, which reduces the accuracy of magnetic detection. Therefore, a comprehensive study of the influence of background magnetic fields on spatial magnetic fields is of great significance. In this paper, a magneto-mechanical coupling model for an oxygen tank is developed based on the improved Jiles-Atherton theory, and the composition of the spatial magnetic field is classified. The influence of the background magnetic field on each component of the spatial magnetic field is simulated and calculated. By establishing the relationship between the induced magnetic field and the background magnetic field, and analyzing the influence of the background magnetic field on the magneto-mechanical coupling effect under specified pressure, references are provided for the magnetic detection.

Key words： background magnetic field ferromagnetic cavity induced magnetic field magneto- mechanical coupling effect spatial magnetic field
