Algorithms for the numerical solution of continuum electromagnetic field problems are based either on differential or integral formulations. The most common approach, at least for low frequency problems, has been the former, using the finite element method. The paper examines the special advantages of integral equations over differential equations, explores some of the difficulties involved and suggests that, in the context of more advanced problems, i.e. optimization and moving systems, the integral equation approach may be particularly effective.
