Abstract
We have presented some results of the investigation of extreme large value of the electrode potential (EP) for the ferromagnetic electrodes in the external magnetic field. The measured EP value is about 20 mV for the Fe-electrode in the magnetic field of 3 kOe, which is three orders of magnitude larger in comparison with the theoretical estimation. The issues presented are as follows: the EP dependencies on the magnetic field for electrodes from various ferromagnetic (Fe and Ni) and paramagnetic (Cu) metals and EP dependencies on the magnetic field for the various types and concentration of electrolytes (FeCl 3 and H 2SO 4). A very significant EP hysteresis and strong EP relaxation for ferromagnetic electrodes have been found and the correlation between them has been discussed. The EP relaxation is measured at different rates of the magnetic field variation and the long-time character of relaxation is observed. The width of EP hysteresis loop strongly depends on the magnetic field orientation relatively to the electrode plane. This fact can be considered as the evidence of the correlation between the EP and the magnetic state of the electrode. This effect can be used either for the definition of the magnetic state of the electrode as well as for measuring the external magnetic field. A model sensor for measuring the magnetic field is proposed.
