An electromagnetic field analysis tool in education

In this paper, an electromagnetic field analysis tool for education in electrical engineering courses which is also accessible from the Web is described. The tool is based on the finite-element model (FEM). However, the main aim here is not to convey the methods of computational electromagnetics, but to give a deeper insight into electromagnetic phenomena. Three examples are shown, an eddy current problem in an axisymmetric ferrite core with air gap and the other two illustrate quasi-static electric transient behavior of the electric field considering imperfect dielectric media.
