To the best of my knowledge, radio waves are generated by an oscillating (or alternating?) electric current, which produces either an alternating electromagnetic field or an alternating magnetic field (can someone confirm which one?) I've heard that the collapse or alternation (can someone confirm this also?) of this generates a radio wave (obviously, with no data). I found this circuit online, and I was just wondering whether it would work, and also how it works (e.g the function of the components, role of the LC circuit).
