Abstract

In this paper, the relation between a magnetic flux decay and a spontaneous spin-up phenomenon of high-beta FRC plasma is outlined based on the research results so far. We propose a hypothesis that an anomalous resistivity produces a difference in the time change rate of the angular momentum of ions and electrons, resulting in the rotation of ions.

Keywords
