Oscillating Charge — E-Field Animation

Initializing...
Heatmap shows log-scaled |E|. Arrows show local electric-field direction. Red dot is the source charge.

About This Lab

This lab helps you understand how electromagnetic fields behave around an accelerating charge. By changing amplitude and frequency, you can observe how field strength, direction patterns, and wave-like propagation change over time. You will build intuition for retarded-time effects, inverse-distance field falloff, and the difference between near-field structure and dynamic radiation behavior in a visual, interactive way.
