For example, if you start to spin a half-full bottle of water very fast on its axis for a long while, and the water gets momentum inside, if you stop spinning the bottle suddenly (the plastic you/the machine are holding),
because the metal with its rotating inertia tenses itself when you suddenly stop the wobble but "unless stopped, things in motion tend to remain in motion", so it dampens the rotation with the spring itself internally,
so that instead of tensing it with a motor rotating it slowly painstakingly, you wobble it back and forth on its spiral center axis, indirectly charging it inside by external wobble instead of direct force,
Lol mixing this, an analogy to mechanics for capcacitance and inductance would be: charging a metal clock mainspring by playing with its inherent internal weight & inertia of the steel (certain case material) it's made of,
I'm talking about Electrolytic capacitors or Supercapacitors, the typical cylindrical ones. Uh sorry to ask now, but you were doing electronics or mechanical related, right? I can't remember now. Sorry if this has nothing to do with your field xD
What would happen with a capacitor-core inductor though? One has to wonder. If it broke the capacitor due to reverse-polarity, flowing AC in the coil, it would mean they in fact interact in some way right? If so, it could be exploited or so?
Basically what I'm saying, what if... take the metal cap off the capacitor and place a flat same-diameter coil on top of the capacitor, on the same axis as the cap's' cylindrical shape. Or what if wire wound around a capacitor simply?
Capacitor would be isolated from any load, so it should charge for sure because it can't leak anywhere? Isn't an open circuited capacitor just a super static electricity accumulator, a giant charged "surfaces" in non-contact by definition?
lol I never thought before that a capacitor could be tried to be considered a "coil" too, not for inductance, but for receiving directly. An external coil will cause internal voltage on the capacitor without a + and - ? Does this even make sense? o.o
What happens if you try to chargea capacitor with an induction coil flowing current, like in a DC transformer in pulses? Will it charge without contact directly without wiring it, as the cap.layers form akind of spiral coil anyway? :o
I remembered the meaning behind my profile image when I ploaded it here. Or I've been reminded, yet again just by looking at it xD. It's to go forward and do interesting things and challenge knowing and improving wisdom, and have a lot of silent fun
