| Voila! The antenna we've made is called a //dipole//. Assuming that its length matches the frequency of the current generator (more on this shortly), and that the antenna is high enough above the ground, you've created a radio wave.((GIF from [[wp>Dipole_antenna |Wikipedia Dipole Antenna]])) As electrons move up and down the length of the wires, they create varying electric and magnetic fields that couple together according to [[wp>Maxwell's_equations |Maxwell's Equations]] and propagate outward in a doughnut shape.((Picture modified from [[wp>Dipole_antenna |Wikipedia Dipole Antenna]])) | Voila!
