This animation visualizes how a half-wave dipole antenna radiates electromagnetic waves. Glowing cyan electric field lines on a dark background show the stages from t=0 to t=3T/8, illustrating how alternating voltage causes inner field lines to curve, pinch near the feed point, and detach into closed loops that propagate outward at the speed of light. It helps students understand radiation mechanisms beyond simple circuit models, useful for electromagnetism and antenna theory courses.

Create a clear educational animation explaining physics concepts step by step for a two-wire λ∕2 dipole antenna. Animate the electric field lines in slow motion showing the detachment mechanism from t=0 to t=3T/8. Show glowing cyan electric field lines on a dark background. As the AC voltage alternates, the inner field lines curve inward, pinch together near the feed point, and detach into closed loops that propagate outward away from the antenna into free space at the speed of light.
