Numerical Simulation of Anisotropic Shielding of Weak Magnetic Fields

In this paper the method of computation of weak magnetic fields in the presence of anisotropic shields it is described. The formulation is based on vector magnetic potential and finite element formulation. Investigation of influence of anisotropic ratio on shielding effectiveness of low level magnetic fields is investigated. At the end some illustrative example in 3D is given and numerical results are compared with experimental data.
