This paper aims at detecting thinning of the back surface of a steel double sided structure. Our proposed technique is characterized by using pulsed eddy current testing with DC magnetization. When a double structural steel is magnetized by DC current, flux leakage is generated as a result of thinning on the back surface. We have shown by the use of simulations that the permeability of the top plate has changed with flux leakage from the back plate. The steel plate without thinning and the steel plate...
