Electromagnetic Methods

  • Chapter
Environmental Geology

Abstract

Electromagnetic inductive methods provide an excellent means to obtain information about electrical ground conductivities. They can be classified as natural field methods and controlled source methods. The well-known natural field method magnetotellurics, used since the 1950s employs fluctuations of the Earth’s magnetic field ranging from 10-5 seconds to several hours to study the distribution of the conductivities with depth (Cagniard, 1953). The electromagnetic exploration methods described in this Chapter are based on the use of electromagnetic fields generated by controlled sources.
