International audienceAn analytic solution to the magnetostatic inverse problem in the framework of vectorspherical harmonic basis functions is presented. This formalism is used for thedesign of a spherical magnetic field compensation system and its performance iscompared with an already existing rectangular coil system. The proposed set ofspherical coils with 15 degrees of freedom achieves a shielding factor of 1000or better in a large part of the volume enclosed by the coils for a dipolar typeexternal perturbation
