https://www.youtube.com/watch?v=qrwAPjfqXNU I wish I hadn't gotten myself banned from physicsforums.com ; they seemed fairly knowledgable; only took 2 days too....

So the theory is, if I have two infinite capacitances on the ends of a coil (or 1 even and just make a LC loop standalone), if I could get a current to flow in the coil, then that current will flow forever, until the voltage of the capacitors is high enough to oppose the flow.. . but if there is no differential to start with, and the capacitance never fills up, the coil would keep conducting. True or false?

if I take a coil and use an external magnet to induce a current in a single direction and stop the magnet in place, this should allow the induced current to flow itself... ?

So I did; I took a 2000 turn 3.3mH air core coil and a 6" magnet and a few capacitors.

The first cap is 9.9nF (12kV?)

the second cap is 100nF (400V?)

the third cap is 6800uF (40V?)

the voltage rating doesn't really matter, I'm not going to exceed a few volts with a hand generator like this.

If it's the voltage difference only that stops the current flow, then a similar motion will generate a comparable voltage; unless voltage is somehow a exponential value of resistance such that 2V is resistance 4x, and 3V is resistance 40x.

(compiling accompanying video; will edit with update)

just musing... Tesla said 'there's no limit to the amount of power you can store in a capacitor'; that can be true if you know the momentum.

wish a I had some of those farad caps to test more.

Current * Inductance : Velocity * Mass

So, I was wondering, how fast does a coil's current increase for a certain voltage X applied to it? I guess it becomes a more complex question because of the resistance of the coil also?

------------------

So in the experiment I was able to charge 9.9nF to voltage 2.2V

I was able to charge 109.9nF to voltage 2V

I was able to charg 1000109nF to voltage 2V (1000uF + )

I was able to charge 6800109nF to voltage 1V (6800uF ) (I think here the resistance of the wire is a total cap on the current that can flow)

In 200ms; my motion from top to bottom is apparently about 200ms.... give or take a little but the same peeks in the middle.

While I was measuring the 200ms time, I inserted a resistor, my first was 10ohm with no effect, my secnod was 100ohm with no effect, but I left it in. (no effect on 9.9nF charge rate or level) but there was a notable effect at 6.8mF the voltage only charged to .25V and was very subdued... which leads me to go back to - the resistance of the coil is going to limit how much it can charge/conduct....

A higher inductance coil allows greater charge... that mobious coil is way better than the solenoid I ran... but maybe if there was a pancake instead? (I don't have a high inductance pancake), the large mobius is about 3.3mH also...

(I should do some math on total joules stored in the caps)

2V 9.2nF

Energy E =

**18.4n Joules**2V 108nF

Energy E =

**216n Joules**1V 6.8mF

Energy E =

**3.4m Joules**3.4m Joules/sec = 3.4mW ; that's pretty straight forward... so these are jouls in 200ms or *5 of the above = watts....

9.2nF 0.092mW

108nF 1.080mW

6.8mF 17mW
