A design sensitivity analysis for optimal shape design of electromagnetic devices is described. The design sensitivity is explicitly derived for two-dimensional electromagnetic systems by using implicit differentiation and direct boundary element methods. The proposed design sensitivity analysis is applied to the optimal shape designs of the yoke of an electromagnet and magnetic pole, and desired distributions of magnetic induction in the air-gap are then obtained
