Geophysical journals were overflown with papers dedicated to different facets of industrial and academic magnetotellurics. When writing the book, we tried to systemize this disembodied knowledge and reduce it to all-sufficient and self-consistent philosophy that can provide the best way to the efficient interpretation of magnetotelluric and magnetovariational soundings. This book may be regarded as a continuation of Berdichevsky-Dmitriev’s monograph (Berdichevsky and Dmitriev, 2002), which presents the foundations of the one-dimensional magnetotellurics. The subject matter of the present book is the two-dimensional and three-dimensional magnetotellurics. We discuss the methods of integrated interpretations of magnetotelluric and magnetovariational soundings and show that a rational use of the magnetovariational data is the key ingredient of progress in magnetotellurics. The book is arranged in three parts. In Part I we consider a model of the inhomogeneous Earth with plane-wave primary field and establish the deterministic nature of the magnetotelluric and magnetovariational response functions – th
