Abstract
A finite element/finite difference algorithm is described for modeling the pulsed excitation of a remote field eddy current (RFEC) probe used in steel pipeline inspection. Previous work has largely been concerned with the steady-state AC operation of the probe and physical explanations, based on finite element studies, of the probe´s sensitivity to outer wall defects. In the present work, the authors discuss the probe response to a sinusoidal pulse and show that such an excitation mode can also be used for outer wall defect detection
