{{#category_index:M|magnetometric resistivity (MMR)}} (mag nē’ tō met, rik) 1.

where Hp=steady-state magnetic field amplitude and Hpo=predicted uniform ground primary magnetic field. Involved in measurements of magnetic induced polarization (q.v.).

2. An electrical surveying method in which the ground is energized with commutated direct current through a pair of widely spaced electrodes and the anomalous conductivity distribution is surveyed by measuring the secondary magnetic field arising from current flow. The magnetic measurement direction is perpendicular to the line between electrodes. This technique is used to explore beneath a conductive surface layer.
