Effects of a Magnetic Field on Current Response of Iron in a Sodium Chloride Solution with Nitrite at Various Electrode Potentials

The effects of a magnetic field on the electrochemical behavior of iron in a sodium chloride solutions with nitrite were studied by potentiodynamic polarization curve, potentiostatic polarization and electrochemical impedance spectroscopy. A 0.4T magnetic field decreased the electrochemical impedance capacitive arc radius at the open circuit potential. A cathodic current was observed at the beginning of anodic polarization curves. The measured current density values in the passive region were decreased after imposing a magnetic field. The applied field increased the anodic current density at high potentials.
