The interaction force between a mica plate and a silica particle in a KCl solution was measured using an atomic force microscope and the difference between the interaction at molecular level in magnetized solutions and that in non-magnetized solutions was examined to clarify the mechanism of the magnetic exposure effects on electrolyte solutions. The data were compared with the results of previous experiments on magnetic effects on colloidal and fluorescent solutions. It was found that (1) the magnetic exposure reduces the potential of the solid surface, (2) the magnetic effect decays with the concentration of alcohol in the solution and the solution temperature, (3) the magnetic effects remain for a sufficiently long period even after the magnetic exposure is completed, and (4) the magnetic effects on the apparent surface potential in this study are consistent with those on the zeta potential reported previously.
