The inductor and wiring are resistors that waste some of the stored energy by making heat so the LC rings and stops ringing soon.
You can see the LC tank as an energy storage. Idealy, when a varying voltage is applied to it, it stores energy endlessly. But in reality the energy is dissipated in the series résistor.
When you say, that it comes to a halt and that the radiation will have a frequency of 1Hz. Do you mean that it will stop oscillating or it will continue to oscillate at 1Hz?
I though that radiation appeared only in resonnance and that out of resonnance there was only heat losses (DC résistance+Proximity effect+skin effect+eddy currents from environment).
An analog way to see it is a baby on a swing. If you push the baby at the right frequency, the swing will go higher and higher each time you push. Same thing with the LC tank, you "push" it at the right moment, so it it stores more and more energy.
But then I don't get it, what force will force attenuate the pendulum. Because if I make the sum with the Laplacian force it won't attenuate it
If provide AC square wave supply, the LC will be tuned at some frequency, so will take that frequency from Fourier series of the sqare wave. But what happends with the other frequencies of the saquare wave written in Fourier series ? Dissipate in heat ?
