Abstract

The principle behind the ac field measurement (ACFM) technique has been explained in [1]. In this technique, a thin-skin eddy current is induced in the metal under test. The current is perturbed by defects in the metal surface and the result is reflected in the magnetic field above the surface. A probe is used to detect perturbations in this field.
