Question

Time domain electromagnetic method for subsurface investigation

Answer 1

Time-Domain EM (TEM) 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.

Transient electromagnetics, (also time- domain electromagnetics / TDEM), is a geophysical exploration technique in which electric and magnetic fields are induced by transient pulses
