Abstract
A wall thinning detection system includes a polarized magnetic charge distribution computing unit configured to compute a spatial distribution of polarized magnetic charges, which is an aggregate of a plurality of magnetic dipoles in a monitoring area, based on a magnetic field distribution in the monitoring area of a metal instrument measured by a magnetic field sensor array comprising a plurality of magnetic field sensors, and a wall thinning distribution computing unit configured to compute a wall thinning distribution in the monitoring area based on the spatial distribution of the polarized magnetic charges calculated by the polarized magnetic charge distribution computing unit.
