WebJul 22, 2013 · The solution of the Poisson equation is plotted as the electric potential contours. Electric field is computed using gradient function, and is also shown as quiver plot. Cite As Praveen Ranganath (2024). Computing Electric field of a double dipole by solving Poisson's Equation ... WebAn electric dipole is mainly two point charges with equal magnitudes and opposite signs separated by a small distance from each other. As an example, let’s try to determine the electric field of a dipole along its axis. Let’s say, z distance from its center. What we have here is two point charges. Let’s say a positive q and a negative q.
