Energy Density of an Electrostatic Dipole
Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
The positive and negative charges are at 
. The potential 
of the dipole in cylindrical coordinates 
does not depend on 
because of symmetry. The graphs show the contour plots of the potential or electrostatic energy density 
in the neighborhood of the charges.
