A Sun-like star undergoes magnetic cyclic reversal shown by field lines colored by the longitudinal magnetic field. Shifts in positive and negative polarity demonstrate large-scale polarity changes in the star. One such cycle is shown, and at the end of the visualization, the magnetic poles are reversed. Wreath-like areas in the magnetic field could be the source of Sun spots which are an important area of study. Rendering was performed through the visualization tool VAPOR using the OpenGL hijacker GLuRay which renders with the interactive ray tracer Manta.
