Abstract
A fluid flow mapper is a visual equipment of electric flux for analyzing electric fields. In this paper, we propose a visualization method of equi-potential lines by using an inversible fluid flow mapper. The inversible fluid flow mapper is based on a fact that streamline and equi-potential line equations of the fluid flow mapper can be exchanged inversely. This method has the advantage of being able to visualize equi-potential lines very easily instead of numerical calculation methods by computer. Therefore, it is concluded that this new method improves the value of fluid flow mappers for electric field analysis.
