Adaption of a numerical technique for solving static field problems to rigid magnets

An intuitive approach to a known technique for solving static field problems is presented. The method itself consists of approximating an integral equation with a set of simultaneous algebraic equations and finding the solution with the aid of a computer. An engineering application for which the method seems well suited is in the analysis and design of devices using ceramic permanent magnets and, for this reason, the paper is oriented along these lines.
