Use of the Electrolytic Tank for Magnetic Problems

Abstract

IT is well known that a convenient method for obtaining the solution of problems of potential theory is to make a model in a water tank in which the equipotentials of the real problem are represented by equipotentials, conductors by conductors and field intensity by current density. Charges, that is sources in the real field, are represented in the model by sources of current, namely, electrodes. This model is satisfactory for any problems involving a vortex-free, but not necessarily source-free, field.
