Abstract: Shielding of low frequency magnetic field represents an important topic of research due to the widespread areas of applications: designing electric, electronic and medical devices, atomic physics experiments, fusion experiments. Recently, possible health hazards have emphasized the interest for the subject.
The lecture will cover theoretical, numerical and experimental aspects concerning the effectiveness of spherical and cylindrical configurations, single or multi-layered.
2D and 3D, linear and non linear finite element numerical models are considered, using nodal, vector and infinite elements. Magnetic and scalar potentials are used and their computational costs are evaluated and compared.
Symbolic computation is used to compute the magnetic field expressions inside the structures. The influence of certain slots on the efficiency of the shields is considered.
