The cosmogonic shadow effect is described, considering charged particles (electrons, ions, charged dust) in an axisymmetric dipole field around a gravitating, rotating body. The medium is two-thirds supported by centrifugal force and one-third by electromagnetic forces under the condition that the magnetic field is strong enough to control the motion. If the electromagnetic forces disappear,

The Voyager 1 Saturn results demonstrate that the macrostructure of the Saturnian ring system can be explained as a result of this effect at the formation of the system. A similar analysis of the asteroidal belt shows that its macrostructure can also be explained by the cosmogonic shadow effect. The observational results show that during their formation both the Saturnian rings and the asteroidal belt passed a plasma state dominated by electromagnetic effects.
