To utilize the inhibition effect of magnetic field on metal dissolution, it was required to be examined in the flowing conditions of solutions. A 100cm3 of 0.015mol dm-3 nitric acid solution for zinc and of 1.5mol dm-3 nitric acid solution for copper and brass were used respectively. The flowing rate of solutions were changed from 0 to 27cm3 min-1. A column with a sintered-glass filter (G1) (10.5mm∅×80mm) was used, and the nitric acid solutions were circulated upward through the column. The dissolution rate of copper, zinc and brass were reduced by the magnetic field effect. The inhibition effect was larger in the solutions in the stationary state or in the flowing solution with low flow rate than that with high flow rate, and it had no dependence on the direction of line of magnetic force. The selective dissolution of crystal planes on metal surface were slightly brought about by magnetic field. The magnetic field activated dissolution of copper in flow of fresh nitric acid solution. The magnetic field effects did not appear in the solution side but in the metal side.
