Re: [TCML] Would a Tesla coil work in a vaccum?-Air core definition



Hi Brian,
The term air core transformer is pretty much understood to mean "devoid of a core material that concentrates the magnetic field"
1) If the term "air-core transformer" is causing consternation perhaps "core-less transformer" or "hollow-core transformer" or even "non-ferromagnetic-centered-transformer would seem better to you? EM energy transfer does not require any physical transfer medium**, but  concentrating the magnetic field through magnetic cores does improve the efficiency of low frequency transformers.

2) Some semanticists would argue that any coil built by the hand of Nicola Tesla could properly be called a "Tesla Coil", but in the last analysis, all definitions are arbitrary, and to be understood by others, you have to use the generally accepted definitions or issue your own dictionary.

Thank you for your brilliant insights!  I asked this as an interesting mental 
xcersize (as I did back when asking if a VDG generator could be used to power a 
C) and am glad for the responses.
 
Getting back to one of the reasons why I initially asked (here it is clarified a 
it)
 
> > With no air for a 'core' (between the primary and secondary coils, those 
eing the only parts in the vaccum) 
> > would there still be streamers off the toroid, same length and brightness as 
here would be for the same

ow, as I have seen on youtube and other websites, some people have called auto 
gnition transformers (which have iron cores, as I have been led to understand) 
esla coils - but then is it clarified that they are not, because a Tesla coil 
s 'air cored', and auto ignition transfromers are 'iron cored' as are the NSTs, 
OTs and BZTs etc we all know so well - the core being the medium through which 
he voltage and amperage are electromagnetically transfered.
 
But if air is not necessary for the coupling to work, if no physical medium is 
equired to transmit the electromagnetic energy - as the absence of air between 
he coils, from what I gather, would not interfere with the  production of 
esonant rise, then should we really keep classifying it as an 'air core' 
ransformer then?  Granted, it is very rare that one hears of a tesla coil being 
uilt in anything other than 1 atm, but I cant help but think that this  is 
ircumstantial.
 
I know it may have been called an 'air core resonant transformer' for a very 
ong time, and old habits die hard, but if having air present between the 
rimary and secondary is not a _requirement_ for it to work - then perhaps the 
air core' part of what we call it should be omitted - or otherwise reflect the 
ature of what is always true about the coupling and transfer of energy from one 
oil to the other - whether in oil, air, or vaccum, just so long as the fluid 
etween the pri. and sec. it is a non-conductive material?
