The application of evolution strategies to the optimal design of electromagnetic devices is investigated. The corresponding field analysis is performed by the finite element method. The strategies involve a simplified simulation of biological evolution. They are especially advantageous in the case of strongly nonlinear optimization problems. The three strategies used are the (1+1), the (1,6), and the (10,100) schemes. They are compared with the Gauss-Seidel method with reference to the example of a dipole magnet to be optimized in order to obtain a homogeneous magnetic field under the pole. A two-dimensional model and a three-dimensional model have been investigated with both linear and nonlinear material characteristics assumed
