The influence of high gradient magnetic fields on the anodic dissolution of iron in sulphuric acid solutions and the localization of the corrosion attack is investigated by means of potentiodynamic and potentiostatic polarization experiments and subsequent surface profile analysis. A localization of the material loss is observed in every potential region of the anodic Fe dissolution except from the passive region. The impact of the magnetic field on the anodic current density and the localization of the corrosion attack are explained by the action of the Lorentz force and the magnetic field gradient force.
► Impact of B on anodic current density and corrosion localization. ► Anodic Tafel region: high dissolution in regions of high B. ► Transition and prepassive region: reduced rim effect by magnetic field. ► No magnetic field effect on the passive state.
