Three-dimensional distribution of the magnetic field and the flux in locally magnetized two-layer ferromagnetic objects

Abstract

Numerical simulation of the spatial distribution of the magnetic field and the flux in two-layer objects is executed. The possibility of measuring the depth of a highly coercive layer on a soft magnetic core by the magnetic field measured on the surface of the object in the interpolar space of a U-shaped electromagnet is theoretically and experimentally shown. © 2016 Author(s).
