  • Coulomb's law
  • superposition
  • field lines

How this runs

The equations of motion are integrated in your browser at a fixed timestep, so the numbers do not depend on your screen’s refresh rate. Nothing is sent to a server. Use Share setup to copy a link that reproduces exactly what you are looking at.
