Abstract: A theoretical and experimental investigation of a magneto hydrodynamic (MHD) stirrer is presented. Such a stirrer can be used to enhance mixing in micrototal analysis systems. The stirrer utilizes arrays of electrodes deposited on a conduit’s walls. The conduit is filled with an electrolyte solution. By applying alternating potential differences across pairs of electrodes, currents are induced in various directions in the solution. In the presence of a magnetic field, the coupling between the magnetic and electric fields induces body (Lorentz) forces in the fluid. Since, the electrodes can be patterned in various ways, fairly complex flow fields can be generated. In particular, in this paper, we describe the induction of cellular motion. This motion can be used to deform and stretch material interfaces and to enhance mixing. The MHD stirrer does not utilize any moving parts. The experimental observations are in good agreement with theoretical predictions.

TL;DR: It is shown that electrical switching of the interfacial oxidation state allows for voltage control of magnetic properties to an extent never before achieved through conventional magneto-electric coupling mechanisms, and suggests a path towards voltage-programmable materials based on solid-state switching of interface oxygen chemistry.
