This paper deals with a numerical analysis system for the magnetic shielding. In the case of construction industry, it is necessary to carefully design the structure with magnetic shielding rooms in order to prevent electromagnetic interference. However, pure iron as the material for magnetic shielding is too flexible, heavy and costly for the components of the structure. To evaluate the magnetic shielding effects, we constructed the system with the program for three-dimensional nonlinear static magnetic field analysis by the finite element method using edge elements for which pre- and post-processors are available on workstations. The nonlinearity resulting in the magnetic saturation phenomena of the magnetic material is taken into consideration in this program. The effectiveness of our system is demonstrated by some numerical results on static magnetic field which is generated by the direct current running through the coil.
