Inductive sensors are used to detect or test magnetic and/or conductive targets. In this paper, a simplified analytical modeling of an inductive sensor having a magnetic core and a conductive shielding is presented with an inspected target consisting in a stratified medium. Two shapes of magnetic core geometries are considered: cup-core and U-core. Comparisons of results obtained using the analytical model with numerical and experimental data show a quite good agreement in spite of the modeling assumptions.
