Abstract

The effect of eddy currents is widely used for diagnostics of conductive materials. It allows to create very simple and inexpensive systems for non-destructive measurements. However, the results of the measurements depend on many factors, including first of all, a conductivity of material and a margin between a sample and a measurement sensor. If both are unknown, it is not possible to evaluate them. The present paper thoroughly reports on an attempt to resolve the influence of the two factors by applying chemometric methods to the eddy current measurements obtained for a set of frequencies.
