Analytical Modeling of the Interaction of a Finite Inducer with a Hidden Long Crack in Ferromagnetic Metals

This paper proposed a semi-analytical solution for evaluation of field distributions around the surface of a ferromagnetic metallic half space, which contains a hidden long crack and excited by a three-dimensional arbitrary frequency current-carrying inducer. The solution was obtained by using the method of separation of variables in three dimensions. This research assumed that the conductor as a lossy dielectric and used the concept of a...
