Abstract
When a sensing coil is exposed to a conducting, ferromagnetic target, the sensing current responds both to the increased self-inductance caused by the presence of ferromagnetic material and to the energy reflected back from induced eddy currents. The general circumstances of composite targets are shown in Fig. 14.1. The current that flows in response to a composite target can be determined by combining the reflectivity phenomena of Chap. 12 with the reluctance phenomena of Chap. 13. (This combination is schematized in Fig. 14.2 as the addition of the vector diagrams of Figs. 12.2 and 13.3.)
