Ferrite Core Eddy Current Probe Model: Description and Verification

Abstract

A model of eddy current probes with ferrite cores has been developed. The model is applicable to axisymmetric cores in the vicinity of a conducting half-space (the work piece). The model is based on modern methods of computational electromagnetics, and is intended to provide a systematic and rational basis for the design and characterization of probe coils. Eddy current responses of four probes on an aluminum workpiece were predicted by the model and compared with experimentally measured responses.
