Abstract
A spheromak is a plasma of ions and electrons formed into a toroidal shape. A spheromak plasma can include electrons and ions of nearly equal amounts such that it is essentially charge neutral. It contains large internal electrical currents and their associated internal magnetic fields arranged so that the forces within the spheromak are nearly balanced. The spheromak described herein is observed to form around an electric arc in partial atmosphere, and is observed to be self-stable with no external magnetic containment.
