Static or alternating magnetic fields may be used to increase the process intensity instead of the mechanical mixing. Static magnetic fields are used as electromagnetic brakes and alternating magnetic fields are commonly used as electromagnetic stirrers. For example, the rotating magnetic field may be used as a non-intrusive stirring device and it can be engineered to provide any desired pattern of stirring. The main aim of this study is to present the results of an experimental analysis of the mixing process under the action of the various types of magnetic fields. Dimensionless correlations are proposed to describe the hydrodynamic conditions in the analyzed mixing system. The results showed that the mixing behavior of the magnetically assisted mixers may be described by means of the term defining the mixing efficiency.
