Abstract
The paper presents a theoretical study of an electrically conducting fluid flow driven by a rotating magnetic field (RMF) in a cylindrical vessel, which is additionally exposed to a constant magnetic field (CMF). As a first approximation of the problem, a self-similar axisymmetric swirl flow in a laterally infinite gap between two parallel walls is considered. A detailed scaling analysis and the results of numerical calculations show that the CMF, which is applied additionally to the rotating one is a suitable tool for changing the hydrodynamic characteristics of the flow due to the RMF and for stabilizing it.
