Electromagnetic (EM) methods measure subsurface conductivity using low frequency electromagnetic induction. A transmitter and receiver coil are used in EM instruments. The depth of discovery is a function of antenna frequency, separation and direction. Soil conductivity is a function of the electrical properties of underground materials and the chemistry of pore liquids and is the inverse of electrical resistance. For this reason, EM methods are very useful in mapping changes in lithology. In addition, EM methods can be used to detect and map embedded ferrous and non-ferrous metals. Enerson uses both Frequency and Time Domain Electromagnetic devices for various applications.
