radio stations broadcast. A radio wave (radiating electric field) propagates out from the source‚ traveling at the speed of light. The source‚ for example an antenna‚ creates oscillating electric(E)/ magnetic(B) fields. These fields are perpendicular not only to each other but to the direction of the traveling wave‚ and travel away from the antenna. The electromagnetic wave is‚ therefore‚ a transverse wave. The electric/ magnetic fields store the energy of the wave. Basically‚ the oscillating current
