Classical hydromagnetic theory predicts that the flow of dilute aqueous electrolyte in a slit can be stabilized by application of a strong, transverse magnetic field. However, recent experiments indicate that stabilization can be achieved with the use of a much weaker field in the presence of a small lateral current. A revised theory describes how the magnetic and electric fields interact to eliminate natural convection.
