Models of the interaction of the electromagnetic field of mobile systems of low-frequency inductive electrical exploration and conducting ferromagnetic bodies

Abstract

The subject of the article is a review of the author's proposed dynamic models of the interaction of the primary electromagnetic harmonic field of mobile electromagneticexploratorysystems and the secondary (eddy current) field of a conducting body with ferromagnetic properties and proposals for new applications of such and similar systems.These models make it possible to theoretically substantiate the shape of the signal from a ferromagnetic body. A signal of this form was often observed by moving systems in practice, but it had no theoretical explanation and was therefore not used. The purpose of the review is to acquaint the wider scientific community with the new possibilities of mobile electromagnetic exploratory systems. In particular, this is the ability of mobile electromagnetic exploratory systems to detect conductive bodies not only with diamagnetic properties, but also with ferromagnetic ones in the ground and water, based on appropriate signals.
