Abstract
Abstract
Most minerals with high magnetism have anisotropic characteristics, and the magnetic field distribution will be affected by topography. Based on the numerical modeling of magnetic field of anisotropic ferromagnetic body, this paper introduces the undulating topographic surface, sets up multiple horizontal planes with different depths between the highest point and the lowest point of the undulating terrain, calculates the magnetic field of these horizontal planes, and finally obtains the distribution of magnetic anomaly field on undulating topographic surface through interpolation. The correctness of undulating topography calculation is verified by comparison with the analytical solution. It is of great significance for inversion imaging of strong magnetic bodies in undulating topography.
