Whether the influence of magnetic field B on the diffusion process during an electrochemical reaction is now well known, the magnetic field effects on the electrochemical kinetics are still a subject of controversy. We have investigated, by means of electrochemical impedance spectroscopy, different electrochemical systems, mass transport controlled, kinetically controlled, and mixed systems, under superimposed B. All results led to the conclusion that a homogeneous B parallel to the electrode surface and varying up to 1 T had no effect on the charge-transfer coefficient.
