The first experimental realization of the multi-coil concept allowed improved shimming of the mouse brain at 9.4 Tesla. The field shapes that can be generated with a set of circular, electrical coils are shown to be much better suited to compensate for the multitude of strong, localized and complex magnetic field distortions apparent in the mouse brain than the conventional, low order spherical harmonic functions used so far.
