The authors propose a new method for visual analysis of electric flux and equi-potential lines in two dimensional electrostatic fields. The method is derived from the study of an inversibility concerning with fluid flow mappers which are an equipment visualizing potential fields. The inversibility is based on a fact that equations interchanged roles of the stream-line and equipotential line equations in the theory of fluid dynamics can express the same fields by replacing the fluid flow conductivities with their inverse, which are corresponding to dielectric constants. In the fluid flow mapper simulating the fields by inversibility, the potential flow changes its direction at right angles for a regular use of fluid flow mappers. Moreover, in order to check the justification of this method, we apply the method to two dimensional fields of dielectric substances with the different dielectric constants. It is shown that the experimental results of the method agree with the numerical solutions by computer analysis and that the method is able to visualize both electric flux and equi-potential lines. Finally it is emphasized that the method presented in this paper can widely expand the ability of fluid flow mapper applications to electric field analysis.
