If the galactic field arose from flux imbedded in the protogalacticgalactic medium, then one would expect this field to be strongly wound up by the differential galactic rotation once it had formed into a disk. This process is balanced by the buoyancy forces lifting the flux out of the disk. The resulting field turns out to be only slightly wound up. Further, its magnitude depends only on properties of the ISM provided that the primordial field exceeds 10–13 gauss.
