TEM (Transient Electromagnetic) is a geophysical technique used to obtain vertical resistivity soundings and a method which responds most strongly to conductive materials. The method is non-destructive and uses a series of wire loops for transmitting and receiving signals in the ground so no marks will be left in the survey area after measurements are finished.
The transient electromagnetic instrument has the advantages that multiple transmitting circuits which reach the intrinsic safe requirement are transmitted simultaneously in the same phase by utilizing the principle of magnetic field superposition in the air, parameters and directions of the coils are both identical, the intensity of the transmitting field is increased, the anti-interference ...

Transient electromagnetics, (also time-domain electromagnetics / TDEM), is a geophysical exploration technique in which electric and magnetic fields are induced by transient pulses of electric current and the subsequent decay response measured. TEM / TDEM methods are generally able to determine subsurface electrical properties, but are also sensitive to subsurface magnetic properties in applications like UXOdetection and characterization. TEM/TDEM surveys are a very common surface EM technique …
Overview. The transient electromagnetic (TEM) method, alternately called time-domain EM (TDEM) or pulse EM (PEM), is a commonly-used, non-intrusive, geophysical method for obtaining subsurface resistivity-conductivity data. Because rock conductivity strongly correlates to rock properties, TEM is an effective way to map changes within rock or soil, ...
