CHAPTER 2: THE MAGNETOMETRIC RESISTIVITY METHOD
The traditional resistivity method maps the electrical properties of the earth by measuring differences in potential at the earth's surface caused by galvanic current flow between two current electrodes. The magnetometric resistivity (MMR) method differs from the traditional method in that the potential electrodes are replaced by a highly sensitive coil or magnetometer and one or more components of the magnetic field are recorded.

Electromagnetic Methods in Applied Geophysics: Volume 2, Application, Parts A and B
Electromagnetic Methods in Applied Geophysics, Volume I, Theory presented the mathematical and physical foundations common to all EM methods. The purpose of Volume I was to help facilitate the understanding of the theory involved and to provide a limited amount of interpretational aids. Volume II, Applications is devoted to a method-by-method treatment of the principal EM techniques in common use.
