Abstract

This paper deals with the analytical and numerical evaluation of the shielding efficiency for the magnetostatic shields. The paper has a teaching purpose. The attenuation for spherical and cylindrical one layer shields was considered. Also the influence of the materials was investigated (non-saturable, saturable and superconductive). Analytical and numerical values were computed and compared and a good agreement resulted. Numerical simulations were performed using finite element method. The thickness and the mass of certain spherical and cylindrical shields were computed and compared. Shielding efficiency for two shell spherical and cylindrical shields were evaluated and compared with one shell shield case.
