Probes,exotic configurations are included. Practically speaking, probes are often composed of more than one coil either for differential operation that is particularly effective in defect detection or so that each coil may be individually optimized for its role as drive or pick up coil. Some probes are of

Flaw Models,he purpose of showing how the various characteristics of a defect (its size, shape, location, and filler material, etc.) influence the observed change in impedance?of the eddy- current?coil. Two regimes are considered: the “small flaw” regime, when the flaw is significantly smaller than the electrom
