Experimental analysis reveals that Lorentz force creates azimuthal and poloidal flows in electrolyte systems, suggesting new insights into electrovortex dynamics.
An experimental electrolyte flow inside a cylindrical cavity promoted by a Lorentz force created by external electric currents and a magnetic field applied in the axial direction is discussed. The Lorentz force produces an azimuthal swirling flow that gives rise to a secondary poloidal flow. Supported by numerical simulations we found that a three-dimensional flow can be interpreted as being partially composed by toroidal orbits. The flows studied have common features with electrovortex flows, and it is expected that this study can contribute to their understanding. Figs 6, Refs 5.
