So the coil acts precisely as if it were a capacitor. That's what
capacitors
do,
store and release charge. Is that what you're saying? Your coil is
getting
more versatile all the time.

I wrote "charge," not "energy." There's a difference. Cecil writes that
current, by which I think he means charge, can flow into both ends of
a coil at the same time. He's right, if he indeed is talking about charge
and not current, in which case, the charge density will increase in some
part of the coil, energy will be stored in an electric field, and the coil will

be acting just like a capacitor (with the capacitance to free space
understood).
