Abstract

In this paper, a 2D electromagnetic finite element model of a pulsed uniform eddy current probe has been developed and it has been used to investigative the effects of the ferromagnetic plate thickness on the corresponding magnetic field .A pulsed uniform eddy current experiment system has also been founded to validate the model. Iron plates are used as the sample whose thickness from 3 mm to 5 mm. The results show that the simulation and experimental results have a very close correlation. The results show that the thinner the thickness of the ferromagnetic plate, the slower the decay rate of Bx. The conclusions indicate that the decay rate of Bx is an important feature for evaluation thickness of ferromagnetic plate using pulsed uniform eddy current.
