Learn what ? What is the purpose of this circuit ?

The purpose of this circuit is to understand how coils work so you can apply that knowledge to other circuits.

The circuit is relatively simple and can be analyzed correctly by anyone who is willing to be careful enough to follow through.  The uncoupled and coupled versions demonstrate several pit falls that various free energy claimants have fallen into in the past.  Even though there is nothing hidden, and nothing left out of the description, more than anything else, the circuit should remind people to test their assumptions and their work.

Okay, here is an attempt to help some people out that may be intimidated by the MOSFET and the switching times and stuff like that.

Attached is a variation on the circuit.  It eliminates the MOSFET and uses a relay, and it's an ideal relay with zero switching times and zero resistance.  Otherwise it's almost an identical circuit.  You notice that a small parasitic capacitance of 100 nF was also added to the circuit.  The capacitance will not fundamentally change what the circuit does.

Feel free to with work with the relay variation of the circuit if you want.  Or work with the original.  Both circuit's behaviour will be quite similar.

I am just going to correct the highlighted comments above.

The capacitance will change what the circuit does.

Both circuit's behaviour will in fact not be that similar.

However, it could still be an interesting exploration but Mark's MOSFET circuit should be the one that is discussed first.

The diagram got a bit more complicated. We have to calculate how long it take to charge the C. When is charging ,the current goes through. Also what is the resistance of he capacitor? That resistance change with frequency. I think in resonance the capacitor has biggest resistance . So we have here in total three overlapping routs for current  depending on the timing. And also on resistance which is not defined? Yes/No /Maybe.

Treat the capacitor as having zero inductance and resistance.  Treat the relay as being perfect:  Zero transition time, zero resistance closed, infinite resistance open, zero inductance and zero capacitance.  Then work through what would happen if we had such perfect components.
