Interactive teaching of electromagnetic field by simultaneous FEM analysis

Electromagnetic theory presents difficult task for the student. The essence of the problem is not the pretentious mathematical treating of the field, but in the field presentation and understanding of field interaction with the material. The paper presents our program tools (FIELD_EDU) for teaching of electromagnetic field, based on the finite element method (FEM). The program concept enables the student to build in the very simple way an arbitrary problem, without being burdened with specific demands of FEM at field analysis. When doing this, the students can help themselves with the library of simple geometrical objects, which have already predefined material properties and boundary conditions. The program tools enable a complete graphical and numerical analysis of one or more examples at the same time
