The Potential Equations of Magnetics
Practically all currently available CAD systems for magnetics and electromagnetics represent physical problems in terms of electric or magnetic potentials. The mathematical physics underlying potential theory, and potential theory as it applies to problems of magnetics, are reviewed in this chapter, with a few brief examples to illustrate the classes of problems to which one formulation or another might apply. The mathematical tools which are subsequently used to solve potential problems are generally numerical. This chapter is intended as a convenient summary review, not as an introduction to electromagnetics.
