We design that a fluid was rotated by a coupling between Lorentz force and a moving force of a electric charge in an electric field. And it generate barrier embedded chaotic flow to use mass difference between positive charge and negative charge of an electrolyte solution. So the electrolyte solution will operate like stirrer in mixing chamber. In addition, it is designed to increase the efficiency of mixing by changing the rotating direction of fluid with a polar switching circuit. In this paper, we present CFD simulation result and mixing visualization experimental results. As comparative experiment with diffusion, We can confirm that The mixer not only have a simple structure compared with former ones but also are able to achieve high mixing efficiency in spite of low power consumption
