概要

This study develops a low frequency magnetic flux leakage testing method for monitoring a wall thinning appearing on the inner surface of a magnetic pipe. We conducted the numerical simulations to evaluate how the presence of wall thinning perturbates electromagnetic fields induced by an encircling coil. The result of the simulations shows measuring the axial component of magnetic flux density enables to detect and evaluate wall thinning.
