The physical modeling method is used to investigate the natural electromagnetic field of a geological medium with anisotropic conductance. A special laboratory installation is used. Scale 3D models of geoelectric sections are created in a 5 x 5 x 0.7 m electrolytic tank. Variations of natural electromagnetic field are simulated by a harmonic plane-homogeneous field. The process of creating anisotropic models of local or regional anisotropic zones of any size or form is developed. The results are presented of analogue modeling of uplift in the upper three-layer section characterized by conductance along lateral axes varying approximately 100 times. MT-sounding curves and the spatial structure of electromagnetic field components of anisotropic and isotropic 3D scale models are compared to estimate the influence of anisotropy.
