The physical modeling method was to investigate the electromagnetic field of a source imitating the ionospheric electrojet on the surface of three-layer horizontally-homogeneous medium which models the Earth's deep section. Magnetotelluric sounding curves and the spataial structure of electromagnetic field components of the auroral source scale model were estimated. A comparison of the results with those obtained in plane homogenous field and in the field of vertical magnetic dipole located at some altitude above the surface of physical model revealed the following regularities. In the electrojet model field, some specific areas are distinguish with the different types of apperent resistivity curves: over a small area under the center of electrojet, the curves of apparent resistivity are identical with thise of the magnetic dipole; over a great territory under the electrojet, the results of MT sounding are similar to those obtained in the field of a plane homogeneous wave; under the edges of electrojet, substantial deviations from the plane homogeneous source are observed.
