Abstract

In this paper a quasi-analytical procedure for the analysis of electromagnetic field distributions in bounded domains relating to linear materials is presented. The procedure allows the determination of analytical expressions far the magnetic fields by means of the superposition of analytical solutions relating to partially bounded domains i.e. half spaces or axially infinite geometries. The presence of ferromagnetic materials is taken into account by means of the determination of equivalent magnetization currents. The procedure can be used for the analysis of different geometries, and an application to the analysis of the induced voltage in a nondestructive testing system is shown
