The bifilar pancake coil at its resonant frequency

[Magluvin]

can a moderator spank TK for this racial remark....I am offended....

Lol

Im not going to remove any posts, and Graham is out on that end, so Brad will have to use his discretion on those things from here on in this thread.

Was being sarcastic....but at the same time was pointing out the obvious....  Folk should be able to say whatever they want....  it's just words....

Your right. Im going to follow that lead here on in.  If it doesnt work out for some then sobeit.

UMmm
I know this is odd
but I should break the Ice [since Grum is on house duty and not  reading ATM

Twas a friend he lost here due to moderating him...not an actual death of a friend

hope that clears that up

he Now choses to not moderate here.

Thanks for clearing that up Chet.

Indeed, thanks to all for the messages both public and private.

One thing that has become apparent is that this community has a heart of solid Gold and it beats strongly.

Kind regards, Graham.

So,things found so far with the BPC

1-Adjusting the frequency can result in either the circuit being more inductive than capacitive,or more capacitive than inductive-we are talking turn coupling here.
At the right frequency,the circuit can be seen as purely resistive,and phase alignment is quite easy to achieve-->power factor of 1.

2-As the P/in is very low,due to using the SG as the P/in source,i switched to 1/4 watt resistors.
With R1 and R2 being 100 ohm's,and R2 dissipating the most power,one would think that it would be R2 that has the highest temperature rise,when in fact,R1,which is dissipating less power,shows the higher temperature gain.After 10 minutes running,where R2 is dissipating twice the power,it's temperature actually drops by 1.5*C below room temperature,while R1,which is dissipating only half the power of R2,rises by 2*C above room temperature.

3- The frequency can be adjusted so as the current flowing through the coil,can flow in both directions at once--some one here mentioned that 
So the current enters the coil in one direction,at the center tap (where R2 is on my schematic),the current is flowing in the opposite direction,and then once again flows out of the coil,in the same direction it is flowing into the coil.
Russ also showed this in his first video reply to me,but seems he missed the significance of this 

I will be carrying out the same tests on a bifilar solenoid coil,so as we can see if the BPC stands alone with the above.

Well
perhaps some perspective
here there are people who pop in and out just for casual interest

and then there are folks who are much more serious [experimenters] who have dedicated huge portions of their life to this "research"
I have found many of the more serious involve their families and share much with their wives and even Kids and grandkids ,its a part of their family experience.

The Kids or grandkids, wives  can read here.

It is true that there are other forums where this is easier to do, however why is it so important to trade street talk for
this??

being able to share this experience with the next generation ,and even with Wives or similar, should not be dismissed so easily

Just one mans opinion
