Abstract
The paper presents a comparative analysis of different ferromagnetic lamina tions used for the reduction of ELF magnetic fields. The investigation is p erformed by means of measures and simulation. The numerical model is based on a hybrid technique coupling finite element and boundary element methods and accounts for magnetic nonlinearities and eddy currents. The results sho w that the use of CO magnetic materials can significantly improve the shiel ding efficiency. (C) 2000 Elsevier Science B.V. All rights reserved.
