(a) A subset from the apparent magnetic susceptibility map of coil 1 from Fig. 3 including core positions (white dots) and selected example profiles for EMI inversion (labelled d/e) and magnetic forward calculation (labelled c). (b) Exemplary magnetic susceptibility values along cores 72A and 78A. Dashed lines display the EMI susceptibility inversion results. (c) Magnetic forward modelled anomaly A (dashed line) based on the measured core susceptibility values and the structure inverted from EMI in comparison to the measured magnetic anomaly (red line). (d) Result of the EMI profile magnetic susceptibility inversion. (e) Result of the EMI profile electric conductivity inversion result. In (d) and (e) all cores are added to the profile for interpretation purposes, as displayed in Fig. 4.
