Testing of multi-coil FDEM sensors on a field model with magnetic susceptibility contrast

Introduction The main advantage of frequency domain electromagnetic induction (FDEM) sensors is the simultaneous measurement of both electrical conductivity and magnetic susceptibility. Nevertheless, this sensor type is still not routinely used in geoarchaeological prospection (English Heritage, 2008). Although both the electrical conductivity and the magnetic susceptibility measurement has been related to electrical resistivity and magnetometer measurements respectively (Kvamme, 2006), these..
