Visualization of Potential Function of the Spherical Region Based on the Green Function Method

The Green Function Method is one of the basic methods of studying the theory of electromagnetic field. This paper, starting from research ideas of the concept of Green Function and Green Function Method, solves the Green Function inside and outside the static field spherical region, based on solution to the Green Function, obtains potential function expression (mathematical model) of static field´s spherical region, then programs the potential function using Matlab, and finally achieves visualization of potential function of the electric charge of the electric field inside and outside the spherical region.
