Abstract
Possible manifestations of the Hall effect in the Earth’s magnetic field during magnetotelluric sounding are considered. Numerical calculations are made for the magnitude of the effect for a three-dimensional heterogeneous earth, using modifications of the Trefftz method suitable for accounting for anisotropy. Versions of the measurement that allow easy detection of manifestations of the Hall effect are analyzed.
