Confirming the Delayed Lenz Effect

[synchro1]

"What was Tesla's intended use for this pseudo-bifilar coil setup? From my recollection in reading the patent he does not say. He describes the fact that it will resonate. Are there other writings that discuss applications? I don't think they were intended to be used as small pick-up coils and driver coils in pulse motors or solenoids, etc. It's possible that this was more like "pure research" by Tesla but I am only guessing".

Look at the top of this Patent. It reads: "COIL FOR ELECTROMAGNET"! Is this what your refering to with that extraneous rubbish you coined to describe it?

Synchro1, all coils are electromagnets with the exception of toroidal coils.

Thanks I went back and read lines 26 to 31 and also lines 43 to 54.   

So it is indeed to overcome capacitor limitations!  You can imagine that 10-foot coil. When it starts to get "really excited" and generate massive voltages it could start to form internal arcing.  So it looks like Tesla took up the challenge of spacing the loops of the coils and possibly adding a dielectric between the loops to make an impressive "self resonating machine" that was not prone to internal arcing.   And then at the end he just says that he has made an LC resonator within the inherent design of the coil.

So there is no planned "killer app" for the coil.  Yes, it generates a magnetic field.

That's the way it looks to me.

Also, just look at how capacitors are made, all the different types.  That kind of tech simply didn't exist in Tesla's time.  It's actually very difficult to make a capacitor at home that has a significant capacitance.  I am not counting the more recent "gray electrolytic goop" stuff that some people try.  I never read those threads so I don't know how successful those attempts are.

That's why this one's special. This coil was labeled specifically for "Electromagnets" may have better been labled anything! Because what else may Tesla really have been thinking? That poses a huge mystery for the rest us, right Holmes? Not so much of a hint of it's intended use?

Synchro1:

You are also forgetting the context of the times.  Almost no one understood electricity.  But they did see electromagnets, in the telegraph office, perhaps to operate traffic lights, etc.  So "electromagnet" was common parlance in those days and considered a new high tech wonder.  You are reading too much into the use of the word.  Try reviewing the material about ampere-turns and visualizing the toroidal magnetic field each loop of wire makes.  All the toroids from all the loops add together.  There is nothing to distinguish the even loops from the odd loops.  They simply all add together to make the toroidal field that the coil projects into space.

I agree with you about Thane's logic.

MileHigh I do see your point about the stored energy, But rather than being stored and resonant as in when there is no load isn't it transferred more directly with no Q ? Kinda like by transformer action.

I am not sure what transfer you are talking about.  I assume that Tesla tried to optimize the Q factor for his setups.  If you can explain more I will try to respond.
