ABSTRACT
ABSTRACT: We are working on non-destructive evaluation of metal quality by the electric conductivity. We use contactless method with eddy currents to probe the metal piece. Here we are testing and verifying the theoretical methods for later use in practical algorithms in fast metal conductivity evaluation. In this particular work we compare the basic eddy current theory of coil impedance with the same scenario modeled with Finite Element Method (FEM). We found very good correlation between the theory and Finite Element Method below 2 kHz.
