An optimum design problem in magnetostatics
ESAIM: Modélisation mathématique et analyse numérique, Tome 36 (2002) no. 2, pp. 223-239.

In this paper, we are interested in finding the optimal shape of a magnet. The criterion to maximize is the jump of the electromagnetic field between two different configurations. We prove existence of an optimal shape into a natural class of domains. We introduce a quasi-Newton type algorithm which moves the boundary. This method is very efficient to improve an initial shape. We give some numerical results.
