The electromagnetic (EM) field method typically involves the generation of an electromagnetic field into the earth to measure the response of the induced secondary field signal. There are two main types of EM method: time domain electromagnetics (TDEM) and frequency domain electromagnetics (FDEM). TDEM instruments measure the decay time of the induced field signal whereas the FDEM method measures the amplitude and the phase of the EM signal. EM data is used to determine terrain conductivity and the presence of metal and is capable of detecting both ferrous and non-ferrous materials in the subsurface. This is important in environmental projects, where detecting changes in conductivity and the presence of metal is critical.
