Dynamic model of a continuity flaw during normal magnetization of a ferromagnetic article: I. Magnetostatic field of a continuity flaw of a finite size
Source abstract
Abstract
Analytic equations are obtained for the calculation of the magnetic-field strength and the density of magnetic charges at the faces of a finite-sized continuity flaw that is present in a ferromagnetic half-space during normal magnetization. Dependences of the components of the magnetic-field strength on the flaw’s geometric parameters and the height of the field measurement are given.
