Аннотация

Due to the presence of strong geomagnetic field, electric currents within the Earth are affected by the appearance of the Lorentz force producing additional extrinsic currents, which contribute to the total measured electromagnetic field. This effect, well known in physics as the Hall effect, is totally ignored in conventional geoelectric and geoelectromagnetic exploration. However, even very general and preliminary analysis shows that this effect is markedly present in geoelectromagnetic signals and, if not being counted, might lead to difficulties or to significant errors in the interpretation. In particular, the Hall effect causes the appearance of the effective anisotropy and magnetization of rocks, which are originally isotropic and nonmagnetic.
