Some superconducting devices like Superconducting Magnetic Energy Storage (SMES) need a small external stray field and sometimes a constant internal field (MRI). Both problems can be approached using special coil configurations. Basic forms like torus, solenoid, and alternate solenoids with parallel axis, are well known. The active shielding method is based on the cancelation of the lower order magnetic moments of a current loop. We propose two designs that handle both problems. One configuration is composed by two spherical concentric distributions of current where a special diameters ratio is determinated in order to realise good conditions for the superconducting windings. The other one is a polygonal structure. The technological approach of these two theoretical designs is considered. The study will focus on energy, flux density and geometrical data.
