INTRODUCTION The immediate objective of a geophysical survey is to obtain some information about the interior spatial distribution of one or more of the earth's physical properties from a limited set of measurements of a related physical field made on the earth's surface (or another accessible place). In the case of an electromagnetic (EM) …

The basic process of generating emfs (electromotive force) and, hence, currents with magnetic fields is known as induction; this process is also called magnetic induction to distinguish it from charging by induction, which utilizes the Coulomb force. Today, currents induced by magnetic fields are essential to our technological society.
