Plasma motions and electric currents in an active region
Abstract
The connection between the proper motions of sunspots and the vortical structure of the transverse field vector and the electric currents of two active regions is investigated. Plasma motions directed at an angle to the magnetic field are found to dominate the entire area of the active region; plasma motions directed along the magnetic field lines occur more rarely. The existence of two global plasma vortices is discovered. One of them is twisted clockwise and covers the entire part of the active region; the other is twisted in the opposite direction and occupies the tail part of the active region.
