Identification of small flaws in conductors using magnetostatic measurements Original Research Article

The identification of small flaws in a conducting half-space or rectangular specimen using boundary measurements of the static magnetic field is considered. The perturbed magnetic field due to the presence of a small flaw is assumed to be generated by an equivalent current dipole located at the flaw position. Explicit formulas are given for the identification of a single flaw or a set of flaws in a conducting half-space or rectangular specimen.
