Electron diffraction imaging shows atomic structure . In this case the atoms are held in an hexagonal arrangement. Unlike the magnetic field of a star, the fixed points of the structure mean that each point . or atom, will have it's own isolated twisted magnetic field. The crystal structure is held firm by the interactions of these multiple electromagnetic fields. A set of rings can be seen in one electromagnetic field where the reducing ratio is .9. Forming designs from the electron fields is a crop circle favourite - it isn't easy though - the crop circle authors know something we don't about this. The concentric circle sets are formed at the intersections of inverse, or reflected, spirals and are on the same ratios as the solar system planetary distances from the sun.
