【 摘 要 】

The previously discovered effect of the corrosive wear increasing of thin-walled St3 steel plates oriented parallel to the magnetic field lines of the Earth's magnetic field was investigated. The remanent magnetization of the samples was measured on a rectangular grid. A relatively large value of the normal components of the residual magnetization was established for parallel orientation of the samples. The slowing down of corrosion is associated with the action of the magnetic field gradient on paramagnetic ions in the electrolyte.
