Digital holographic study of the effect of magnetic field on the potentiostatic current oscillations of iron in sulfuric acid
چکیده انگلیسی

The effect of magnetic field on the potentiostatic current oscillations of iron electrode in 0.5 mol dm−3 sulfuric acid was studied in situ by digital holography. The orientation of the magnetic field had an obvious effect on the current oscillations: when the magnetic field was vertical to the electrode surface, the magnetic field would cause a cyclotron-like fluid flow of ions and had a negligible effect on mass transport and the oscillations; when the magnetic field was parallel to the electrode surface, the force would drive the charging ions to one side of the electrode and increase the mass transport, resulted in a decrease of oscillation period. The effects were analyzed by holograms and discussed by means of magnetohydrodynamic force.
