Abstract

In this paper, we propose and develop a device for visualizing the magnetic field produced by ion transportation in electrolyte cells. Using 0.5 mM potassium ferricyanide (K3[Fe(CN)6]) dissolved in 0.5 M sodium sulfate (Na2SO4) as the electrolyte, the magnetic distribution was obtained using high-TC SQUID scanning performed by a planar gradiometer located above the electrolyte cell across the surface. The difference in the ion transportation path in the electrolyte cells is discussed with regard to flow channels fabricated in the electrolyte cells.
