Concentration boundary layer formed in the vicinity of copper anodic electrode having a shape with triangles aligning in line located in a transparent electrolyte aqueous solution was observed under the imposition of a static magnetic field to clarify the effect of vibrating electromagnetic force on the boundary layer. Two current patterns of DC current and superimposition of AC and DC currents were adopted. The concentration boundary layer thickness at the right and left sides of a valley between the triangles of the anodic electrode were not the same under the imposition of the DC current because of difference of electromagnetic force direction between on the right and left sides of the valley. On the left side of the valley, decrease of the brightness in the concentration boundary layer under the imposition of the DC current was larger than that under the imposition of the AC and DC currents where decrease of the brightness corresponded to the amount of reaction products. This is because the AC and DC currents mixed the dense and dilute liquids of divalent copper ion around there. On the contrary, decrease of the brightness in the concentration boundary layer under the imposition of the AC and DC currents was larger than that under the imposition of the DC current on the right side of the valley. The reason can be explained as follows. Because drastic dissolution of divalent copper ion from the electrode and a strong electromagnetic force were simultaneously excited, dense liquid was transported far away.
