Electric Field Visualizer
Point charges in 2D with electric field lines or vectors computed from Coulomb’s law. Add, move, or flip charge sign and watch the field reconfigure.
Who it's for: E&M intro; visualizing superposition of fields and symmetry.
Key terms
- Coulomb’s law
- electric field
- superposition
- field lines
- point charge
How it works
Point charges in the plane (Coulomb model). The electric field E⃗ at each grid point is the vector sum of contributions qᵢ r̂ᵢ/rᵢ² (same direction as in your textbook). Arrows point in the direction a positive test charge would be pushed.
