Electrolysis in Magnetic Fields.

摘要

In addition to the results on the Leclanche cell, significant progress has been made on the experimental studies of the influence of magnetic fields on the electrodeposition of copper and of chromium. In the case of copper deposition, experiments have been performed with a long, glass cell, which was designed so that either the anode or the cathode could be placed in a magnetic field, the strength of which could be varied from zero to 13.4 kG. In this way it is possible to determine the effect of the magnetic field on each electrode process and to compare these results with results obtained when the entire cell was located in the field. The results of these experiments clearly show that it is not necessary to have the entire cell in a magnetic field in order to obtain the desirable results which were reported previously. When the anode is in a magnetic field, the uniformity of dissolution is enhanced. When the cathode is in a magnetic field, the uniformity of deposition is enhanced. The reduction in cell resistance appears to be caused solely by interaction of the magnetic field with the processes at the cathode. The significance of these results is that the benefits of magnetic interaction with electrolysis can be obtained by incorporating into the electrolytic cell a means of applying a magnetic field at each electrode.
