  • Electromagnetic problems The electromagnetic theory has been fully developed into a mathematical equation system by Maxwell in which he succeeded to explain all physical phenomena. One could ask why after 200 years it is still impossible to accurately solve these equations. The explanation is given by the fact that a solution in a closed form is impossible due to the presence of anisotropic, non‐linear materials with a difficult geometrical shape. Until the sixties, emphasis in clectromagnetism was on finding extremely difficult test functions, offering a solution for a limited category of problems. Examples are the rotating field theory in electrical machines and the wave equations in high voltage line transients.
