Hi Icarus,

So you are saying that when the collector coil is inside the control coil, you get larger spikes? Do you have a scope that you could take picture of and post here? Did your bulb appear to have any difference in the glow when the collector was inside the coil as opposed to not.

One more recommendation. If you can get the pulse width down, you may get better effects with less current dissipation through the coil.

@Otto, I recommend that you bring your pulse width way down from 50%. You can get better radiant results that way and use much less current from your power supply. Just a thought.

My second mis-replication of Otto's little coil on the Lords of the Ring topic agrees with you.  I was sweeping the pulse-width when I found the sweet spot.  Post frequency adjustments did not seem to move me out of this sweet spot, as I recall.

EDIT ONE: I just checked, post frequency adjustments did not move me out of this sweet spot.  In fact they seem to have little effect on frequency at all.  The frequency is actually oscillating; it looks like a spring on my scope bouncing back and forth.

Hi Rosphere,

Absolutely correct! Once you get the pulse width right, the changing the frequency only gives you more pulses to work with. But when you get close to the coil's resonant frequency, the kicks will start to add into a humongous sine wave when the coil is at resonance. Unfortunately, I have not had the chance to dabble in teh coils actual resonant frequency since most of my coils' resonant frequencies were up in the MHz above my signal generator's range.

The tall kicks are a BIG key! High voltage low current.

God Bless,

Thanks Jason...again

For you paitence to explain as well.

Please see this effect that Jason has 
Im sorry If I seem unhelpfull to some.. it has been a while now and this experiment is quite oldasfar as otto would be concerned. It demonstrates that frequencies can misbehave in a coil...Just a first step.

Please recognise just how hard it is to get to here.and this part is simple...or so it seems looking back?
Now apply this to what Steven has been saying and you will see the difficulty involved..and the patience required.
Yes mine runs out too early at times... been here a while now.

Some people who have just arrived are not aware of things that others who have been hunting for a while are.



Cheers

OTTO,

Hate to ask these questions, but nit-picking engineer's need this level of detail.

How is the "50 turn" coil wound?  Which direction in reference to the wire that goes through it?

Also, is this 50-turn coil just a lump of 50 turns or does is have a length - like a solenoid coil.

If it is like a solenoid coil - single layer or more than one layer?

Inner and outer dimensions of the 50-turn coil?

(Might be easier to post a picture of it or make a sketch than to describe it.)

For duplication of an effect - you need to get as close as possible to the original experiment.  If you ever invent anything, this sort of detail in a lab notebook will go far to prove that you invented it.  This is also good for general experimenting.  Things appear one way today and then test tomorrow change your view and you can go back and compare the differences in setups.  Scientist would disect you setup down to the wire length, insulation type, copper alloy, and everything else.
