The bifilar pancake coil at its resonant frequency

[synchro1]

Back to your old pattern of misrepresenting my work and that of others, I see.

Pomodoro, I encourage you to do your own testing of the claims made by synchro1.

"eats up" ? You mean that you _fed_ the bifilar coil with twice the power of the monofilar coil in order to get it to pick up more paper clips. You did this by increasing the voltage supplied, which in turn increased the current through the coil. DUH... of COURSE you will get a stronger field in this case.

With the _SAME_ current fed to both coils they will both have the same magnetic field produced and will pick up the same number of paper clips. Of course using iron/steel nails for this moronic test will skew your results because you are magnetizing the nails themselves, and probably also your paper clips.

Look at my hex nut and Leedskalnin locking videos. Snap charge and pulse magnetization is a natural event. Twice the current spontaneously jumps from the battery into the bifilar when the electrodes swipe the battery terminals and the iron nail core instantly maqgnetizes to twice the strength of the single wire core. The bifilar really pops compared to the single wire coil. You yourself mention the effect in your bifilar to single wire coil comparison video, and it's clearly visible to the viewer.

My advice to you Mr. Hogwallow, is to measure the inductance in Henries of both the bifilar and the single wire pancake coils with an inductance meter and see for yourself what the difference is.

Tesla bifilar coils have twice the inductance of single wire coils of the same gauge and copper weight

This is FALSE.

Still misrepresenting my work. And I've made the measurements, as you can see.

Take your own advice and do the measurements yourself... which you have clearly never done.

"swipe the battery terminals".... that's laughable. You have no idea what current you are putting into your coils or whether you are equalizing conditions. You really need to learn how to do experiments properly and how to MAKE MEASUREMENTS instead of spouting nonsense.

Anyone tried making an electromagnet?, Some internet sites claim tesla's bilfilar winding with the same number of turns makes for a much stronger pull, lifting way more paperclips. Since its DC operated it cant have anything to do with resonance or extra capacitance. I'll give it a go soon myself cause you can't trust all the creeps out there,  but if true, what would be the reasoning behind its extra performance with I'm assuming the same current?

Yes the field is stronger. Also, with a DC measurement, the resistance is differnent compared to a normal coil. This video shows it clearly:

Tesla explains it in his patent (512340):
In electric apparatus or systems in which alternating currents are employed the self-induction of the coils or conductors may, and, in fact, in many cases does operate disadvantageously by giving rise to false currents which often reduce what is known as the commercial efficiency of the apparatus composing the system or operate detrimentally in other respects. The effects of self-induction, above referred to, are known to be neutralized by proportioning to a proper degree the capacity of the circuit with relation to the self-induction and frequency of the currents. This has been accomplished heretofore by the use of condensers constructed and applied as separate instruments.

My present invention has for its object to avoid the employment of condensers which are expensive, cumbersome and difficult to maintain in perfect condition, and to so construct the coils themselves as to accomplish the same ultimate object.

To me this says the bifilar coil, is dodging lenz law (which isnt a law, but a observation)

@ tinselkoala & sychro1
The Bifilar (pancake) coil is mostly different in the capacitance, between the windings.

Its about the stronger dielectric field.

The difference of the magnetic field strength comes from the absence of the Lenz "law" effect, that in a normal coil gives a counteracting magnetic force, weakening the field (eating power). The dielectric field prevents this action (according to teslas patent as citated before)
