The superconducting solenoid magnet for high-energy physics or the magnetic-resonance-imaging systems uses an iron shield to enhance the central field or to shield the strong leakage magnetic field. The design of the shape of the shield has been difficult, because the iron has nonlinear permeability. An optimizing procedure for the shape is proposed that is based on a hybrid finite-element-boundary-element method (HFB method). The HFB method is suited to analysis of problems which present nonlinear behavior and extend to infinity.
