Electrostatics / Charge comparisons

Four point charges in 3D

Explore four point charges. Choose a setup below to compare the symmetric baseline with stronger individual charges or pairs, then rotate the view and follow the field lines.

Baseline +1 at (1, 0, 0) and (−1, 0, 0)
Baseline −1 at (0, 1, 0) and (0, −1, 0)

Read the field. Arrows follow the electric field. Lines connect positive to negative charges or continue toward/from infinity. Line colors show field strength. Select one path to inspect its connection; use the button to reveal local equipotentials.

Read the model. These are fixed points in vacuum. The baseline uses symmetric ordinary paths, avoiding critical directions. Camera views are finite windows of an unbounded calculation. See the baseline 2D slice or assumptions and validation.
