Complex Susceptibility Measurement Using Multi-frequency Slingram EMI Instrument
Abstract
Complex magnetic susceptibility is a well-known property both theoretically and experimentally. To achieve this measurement, different ways have been tested, like TDEM or multi-frequential measurement on soil sample. In this study we carry out the measurements by the use of a multi-frequential EMI Slingram instrument to collect data quickly and in-situ. The use of multi-frequency data is also a way to correct effects of the conductivity on the in-phase component and effects of the magnetic susceptibility on the quadrature component of the raw signal.
