Application of Solution Stirring Action Caused by a Longitudinal Magnetic Field to an Electrochemical Experiment

—Assuming a Microscale Electrolysis Experiment—

Abstract

In this study, the effect of hydrodynamic flow using Lorentz force has been verified to provide a new method of stirring a solution for an electrochemical experiment in science education. As verification, an electrolysis of KCl aqueous solution has been carried out using Al electrodes under a longitudinal magnetic field in the well of a well plate, assuming a microscale electrolysis experiment. The outcome confirmed that applying an electric current to a solution leads to a swirl flow within the solution, with the result that the whole solution becomes effectively stirred. This study suggests the possibility of the useful application of a solution stirring action caused by a longitudinal magnetic field in microscale electrochemical experiments.
