The flow of an electrolyte solution can be observed when electrochemical reactions occur at electrodes under a magnetic field. This phenomenon is due to the Lorentz force working on ions involved in the electrochemical reactions. To date, several investigations have been conducted on the use of this phenomenon as a visual educational tool to promote understanding of the Lorentz force. However, there remain many problems to be solved regarding the aspects of generality and simplicity. For this study, a new visual educational tool was devised and, subsequently, its practical usefulness was confirmed through a preliminary experiment and verification classes. As a result, it was confirmed that the new visual educational tool can be made using aluminum as the electrodes and a sodium chloride solution as the electrolyte solution. By utilizing these materials, it is possible to efficiently foster a deeper understanding of the Lorentz force among students.
