The bifilar pancake coil at its resonant frequency

[tinman]

One thing is for sure-->those who continually dismiss the PM and water as an endless power source,will be the very same people that will go no further than they are now.

One has to have a good laugh,when you hear from others,that the PM can do no useful work--and yet they are the very same people that do not yet understand what the magnetic force actually is 

There is a big difference in knowing what we can and cannot do with a magnetic field,and actually knowing what it is.
Only when you know what the magnetic force is,will you know what it can do--until then,it's just some fumbling around,and using what we know so far.

Anyway,back to my washing machine motors for me.

MH, Tk, Zephir and all,

First let me say that I appreciate the constructive and well meaning criticism that you offer as help to those such as myself.  My goal is to simply continue to seek answers for those seeming anomalies which might provide a self generating device.  My post of the MEI scope pix was one such example.  Do I plan to attempt to build a looped version to really prove or disprove the concept, absolutely.

Also, I have the highest regard for the engineers at Tektronix.  I have worked directly with them regarding measurement issues with my MDO3034 and they have been most cooperative.  The newest series of their scopes are quite capable of reasonably accurate measurements if used properly, but improvements could be made especially when measuring in circuits with COP~>1.

In the recent past I made a promise to myself that I would no longer post to any forum unless I could demonstrate a self runner of some type.  All else is futile so I will attempt to return to that position.

Another quote form Tesla's patent 512340 (bifilar coils):

I have found that in every coil there exists a certain relation between its self-induction and capacity that permits a current of given frequency and potential to pass through it with no other opposition than that of ohmic resistance,

or, in other words, as though it possessed no self-induction.

This is due to the mutual relations existing between the special character of the current and the self-induction and capacity of the coil, the latter quantity being just capable of neutralizing the self-induction for that frequency. It is well-known that the higher the frequency or potential difference of the current the smaller the capacity required to counteract the self-induction

I am going to assume that Tesla had a strong intuitive sense and understanding of what he was observing and analyzing and applying, but he did not have the circuit analysis theory or applied mathematical background to model these systems.

The actual analysis and modeling has been around for a long time.

"Therefore the series LC circuit, when connected in series with a load, will act as a band-pass filter having zero impedance at the resonant frequency of the LC circuit."

https://en.wikipedia.org/wiki/LC_circuit#Impedance_2

"The parallel LC circuit connected in series with a load will act as band-stop filter having infinite impedance at the resonant frequency of the LC circuit. The parallel LC circuit connected in parallel with a load will act as band-pass filter."

The only exception seems to be the ones that stubbornly stick to the idea that the current reverses when the coil discharges.  For some people there is no hope they will ever learn.

Hi Caroll and everyone. Hi T.K.

Just to share my point of view on this reversal never ending story.

We feed some dc current across an inductor to ground (-) through a switch. For example a low side mosfet switch. When this current flows, we have a certain magnetic polarity across the coil. During this time, inductor 'pushes' as to oppose to this current flow, developing a voltage polarity opposite to that of the source. When switch opens and current stops flowing, in fact there is a violent change in the ''magnetic moment''. Where North was before, now there is a sudden movement to zero. Inductor sees this change and develops instantly a counter electromotive force opposite to the one that had before when it was pushing against battery. This new coil's voltage polarity, which now is a HV spike, tries to maintain the same current direction as when current was moving. But now it is just opposes again to the sudden zeroing of current and consequently the rapid change in flux. 

The best proof for the described action, is to ''see'' straight across a secondary with your oscilloscope probes. You will see that cemf changes direction between charging and discharging actions of the primary.

So my answer to the question about if current changes direction or no: There is not any conduction current when switch opens! Just the reaction of the opposing in nature coil, which is pure voltage.
The argument is based on a wrong base.

Mr.Nelson Rocha I have a lot respect to you as you have posted in your recent long post.


It has to be best written opinion on Over-Unity here. 


This is not a place to "learn " as the resident trolls will destroy you here for being uneducated ...


They simply are will not allow any one any help or even suggest that..


They will  dig a hole for some one to fall in and trap him in that with no way out ..


Again a fantastic post.. Kudos to you and that you have the passion to to that !!!
