Abstract A formula for magnotic-induced hydrogen evolution overpotential was proposed.Cathodic polarization curves for iron in hydrochloric acid solution of different concentrations (0.05,0.2,1 mol/L) at differeat temperstures (25,40,60℃) were measured in the presence of magnetic field of 0.4T (tesla).The dependence of on temperature and hydrochloric acid concentration was obtained. Such a relationship was interpreted from the point of view that varistion of hydrogen ion hydration caused by changes in environmeat might alter the structure of electric double layer.

Key words: Corrosion of iron in hydrochloric acid Effect of magnetic field Magnetic-induced overpotential Hydrogen evolution
