This branch introduces an enhanced version of the point charge simulator that accounts for the retarded (delayed) electric fields using Liénard–Wiechert potentials. This allows for a more realistic simulation of moving charges and their effects on the electric field.
- Retarded Electric Fields: The electric fields are calculated using Liénard–Wiechert potentials, considering the finite speed of light.
- Dynamic Visualization: Visualize the movement of charges and the corresponding electric field lines in real-time.
- Interactive Charge Placement: Add and move charges interactively with mouse input.
- Speed Indicator: Displays the velocity of the moving charge relative to the speed of light.
