Biggest thing to grasp here is were not running e- electrons/power into our setups.
Of course, I do know that.
I am not sure however the juice will stop when the gap is open.

My tests are making me think otherwise. If anyone is looking for a good project this weekend, it might be time to see if you can make the charge stop once the battery is wet.
When i hear those words i think this

Electromagnet- coil with iron core

Choke- Coils ususally wound on a ferrite toroid to filter rf can be built other ways tho.

Induction Coil- Air core'd coil possibly bifilar depending on self inductance attributes desired
Good, now we won't bark at each other. I may still use the words my way and I will keep a copy of this for cross reference

I have been thinking of making a coil gun. Thanks for the instrux.

I agree that the magnetic pulse may not compleetly stop when the terminals are disconnected-  I Think of pulsing the secondary as pushing a swing same push higher result each time.  So the variables to work with are
the intensity of the repeated push "power in the primary" 
the time between pushes - how quickly the gap fires makes and breaks the connection

Now eventually if the person on the swing was light enough and the person pushing was doing so syncronosly the swing would start going in a 360 degree circle not just swinging back and forth anymore.  The same push is accelerating the "particle " in a circle now not just a swing up and down.  Now think of inerta  when an object/particle moves in a circle ever increasing in speed/voltage... and retaininig a little spin until the next push because of centripical force.  this applies to our exp. 

@MrSpates:  Did the coil get hot before the graphite rod got hot?  And what was the frequency of your AC voltage?


I don't know, they both got hot all I know is I unplugged it when the electric tape holding the wire ends on the rod started to melt.I also built one with an iron core and while it worked fine as a magnet, it too got hot. I don't know enough to test frequency on AC. i.e I don't have an oscilloscope. I was using power from an old old toy train transformer which runs from about 5.6vac to 15.9vac.

Hi all,

Last week I had the suggestion to make a regular induction type coil to compare with the NS type things I was testing. I did. I didn't get much for results which made me realize my secondary needs more wire etc.

But the other thing about it is that with only copper wire, I couldn't do some of the more bizarre tests that I had done with my bimetal bifilar coils.

So, in the last couple of days I took apart that control and made another control, but this time a bimetal bifilar. This has the wires wound clockwise down to the bottom then straight back up as is conventionally done with electromagnets with multiple layers. I used the same amount of copper wire and ran it bifilar with an equal amount of iron wire. I was then able to make some tests.

Without going into the detail I will say that this performed about the same as the wound down and back.

Since it has the 4 wires, I was able to do the squeeze test on this also. And it also showed an amplification of voltage.
--------------

I would like anyone else interested to try this squeeze test on your NS coil with and/or without secondary. It is a simple test to do. Here is how:

With the dmm set to mVDC squeeze the black probe with your left hand fingers. and the red probe with your right.

Do it again with moist fingers.

Now clip the dmm probes onto the 5,6 .  Clip the red probe on copper and black probe on iron. Squeeze the loose wires the 10's and read the voltage.

Repeat this with fingers moistened.
(I used saliva because it is readily available  )


I think you will be impressed.

I am asking someone to do this for a repeat of the test.
Is anyone game?

@ Jeanna

How much voltage did you get from the squeeze test?
