In this paper, we calculate the electric cell voltage of the physical circuit at etching of ferromagnetic electrode in the form of a cylinder in an electrolyte caused by inhomogeneous distribution of concentration of the paramagnetic corrosion products on the surface of a steel cylinder in an inhomogeneous magnetostatic field. The shape of the electrode was chosen because all points of the cylinder surface are equivalent in this model system in the absence of magnetization and effects of the magnetic field can be easily separated from the effects of a different nature. The current density and Lorentz force are calculated in an electrolyte in the vicinity of the magnetized steel cylinder. The Lorentz force causes movement of an electrolyte perpendicular to the direction of the external magnetic field along the cylinder axis. Comparison of calculations with experimental data allows concluding that a certain part of paramagnetic ions in the electrolyte in a magnetic field represents the nanoclusters of paramagnetic ions, which can be for example nanobubbles. The results of the theoretical modeling can be used for creating functional materials by means of magnetoelectrolysis and for modeling of the influence of the biogenic magnetic nanoparticles on transport processes and biochemical reactions in cells of live organisms.References
