Numerical modeling of an eddy current sensor used in a metal separation device

This work deals with the numerical analysis of the electromagnetic field problem for one proposed Ferrite — Cored Eddy Current Sensor, using the Quick Field software; this sensor can be used in the waste management for metal separation. Using this software, many specific cases are analysed, namely, when sensor probe coil is placed on different types of metallic samples (ferromagnetic and non ferromagnetic); due to the magnetic flux of the induced eddy currents in the metallic samples, the changing of the coil parameters values and the currents passing through the coil versus supplied voltage frequency are presented and discussed.
