Abstract
Plots of flux tubes in axially symmetric static field problems are ordinarily obtained by rather tedious methods from plots of the equipotentials. The differential equation for the flux function in circular cylindrical coordinates does not have the same form as Laplace's equation. Hence, an ordinary wedge‐shaped electrolytic tank cannot be used directly to plot flux tubes in an axially symmetric potential field. A direct method is described making use of a coordinate system in which Laplace's equation has the same form as the flux equation in the cylindrical system. An electrolytic tank can then be set up which makes use of this coordinate system in plotting equipotentials which are the analog of the flux tubes in an axially symmetric problem.
