Magnetic field effects on anodic oxidation of potassium iodide

External magnetic fields (less than or equal to 6 kG) significantly increase yields of I-3(-) and H-2 as well as oxidation currents in anodic oxidation of potassium iodide. The Lorentz force on ions in the solution induces convection of solution, resulting in acceleration of the entire reaction rate. This is further confirmed from the observation that reddish-brown streams of I-3(-) in the solution, moving downward at zero field, undergo turbulent motion in magnetic fields.
