Borrowing concepts from the Electric/Plasma Universe theories [1], I examine a possible explanation of at least part of the observed behavior for the galactic rotation anomaly for spiral galaxies by considering an idealized case where the combined magnetic fields from the galactic core (assumed to be a rotating charged sphere) and spiral arms (assumed to be a rotating charged disk exhibit a trend toward the ‘flatness’ in these rotation curves as one proceeds outward radially from the galactic core to its edge. This hopefully is a plausible addition to the various alternate explanations for this anomaly that do not invoke the likely fiction of ‘dark matter,’ alleged to comprise roughly 85% of the total matter in the universe (and, with the other likely fiction ‘dark energy,’ alleged to comprise roughly 95% of the total mass-energy of the universe). In the process, I provide at least an introduction to some of these other alternative explanations for the galactic rotation anomaly.
