Didn't ask you to, nor did I suggest you tread on rose peddles! 


I can read Brad, I know who said what and when.  My comment was general, if I were referring to you I would have mentioned your name in the post.  However, in light of being accused of something I didn't do, I recommend that if the shoe fits wear it.  You didn't find your name in my comment, you therefore assumed that I was referring to you, ego....your mistake.   


It would be awesome to see all this going somewhere....as it stands, I have yet to see anything that hasn't been demonstrated countless times already.  Where is the real?  There is no research taking place here, by the book or otherwise.  All that's going on here is position defense, and it matters little to me how you react to this, I stated this before elsewhere, you were a guy that had an eye for certain things, and that guy I have not seen in quite some time.  Each time I think its time to show you shit that I have shared with a few of your peers, you show me that it would be a complete waste of time, unfortunate, but it is what it is. 


No matter how the magnets are oriented, circuit geometry demands that CEMF limits current.  Current is, but should/must not be limited in this manner.  You really want to see your magnets do work, rework the circuit, allow for a path from the magnet into the coil and back (this opens the door to 180° shifts, but not like how its being discussed, and when that which is being discussed is applicable, how this understanding is applied is questioned).  As long as your current is being limited by CEMF, the magnets will not work with you, nor you with the magnets.  When increasing CEMF is of such a direction so as to augment the applied EMF,and thereby, increase consumption, (not covered in the texts books I have read) can one begin to contemplate how the magnets under this new set of circumstances can perform real work in broad sense of the term.  The general rule should be that a magnet cannot work for you if its working against you.


How we choose to view coils sets the stage for everything that follows that decision.  Part of what I see are flux gates,  our collective lack of understanding keep us from using them in a manner which results in the force we call attraction from manifesting between inducer and induced inside generators.  Repulsion is a no brainier, for that all you have to do is what you are told, the law takes care of the rest.  There is way more going on than these various debates will allow the free thinker to ascertain let alone believe.

Cheers Erfinder :)

I am always looking/researching,and experimenting with the unknown--of course you know this.

But ATM,i need to take action against that poor excuse for a human being.
There should never come a time where a member of this forum should recommend that one experimenter should not help another,nor should members here be exposed to the profanities used by said member.. This is the very heart of these types of forum's-where those that know could be asked for help by those that are still learning the ways of !!known! science.

I will keep on doing what i am doing,despite having to deal with this fraud.

Meters can't give us any insight into those areas we have yet to consider.  Perhaps more time and energy would be better invested in contemplating the ifs, rather than defending a point which, were it self evident, requires no defense.

I totally agree with this Erfinder,but the point i am going to make here,is that we should not stand for--oh that is wrong,but i will not provide any proof to the contrary. To many times we have seen self acclaimed ex-spurts(such as before mentioned) reel out all sorts of rubbish to try and misdirect others from knowing the truth. The !no resonance! in and around the ICE rubbish had to be stopped,and i did that. Now said negative claimant is out to do what he can to once again misdirect and encourage others to avoid helping a fellow member on this FE research forum.
Im sorry,but that stops right here in this thread,and said idiot is now in the spotlight--the very same place he put EMJ in some time back--and continues to gloat about it.
Well now it's his turn--now we get to judge him as he judged EMJ.

If MH has his way,then you may actually be correct for once :D

As you are the person that felt he was high enough up the food chain to judge me on my understandings on induction--but of course ,failed to answer a simple induction question,i offer you the same questions i asked MH.
Feel free to answer the questions any time--as long as it's before anyone else dose.

Cool.
So as you feel that you are full bottles on magnetic field's,please tell us all here what it is--what is the magnetic field/force that surrounds a permanent magnet?.

You make lots of comments and determinations minnie--but never can you back them up with your own smart's.
There is a name for that kind of person--what was it again?. ::)

To say i am wrong,or that the scope capture was wrong for the question asked,is also to say that PW and TK are also wrong.
The scope capture and schematic would be 100% correct if it was denoted with either dot convention on the transformer, OR stated that CH2 is inverted. What part of that are you having difficulty understanding?

So please do not do what MH dose,and add confusion by way of saying things are wrong by pointing out things that were never part of the question.

Brad
How is it that I am adding confusion? Tell us then, if someone built your circuit and placed the probes precisely as you have, and did not invert their scope channel nor flip the transformer leads, would they produce the same wave form as you showed? Will they not be confused when they see the secondary voltage leading the primary current?

I nor PW and TK any any difficulty using the associated scope shot to answer the question asked. The scope shot presented was correct in that it provided the needed information to answer the question. The question was presented to minnie,in order to determine if he had the smarts to make judgement on me,and my induction skills. CH2 was inverted for this very reason--so once again,the scope shot is correct for the question asked.

Because the question was aimed to determine whether minnie had the skill set to pass judgement on mine. It was not suppose to show a correct or incorrect polarity of channel inversion. It was set like that as a test,and a question was provided in regards to that test.

No they would not. But  if the same question i asked was associated with there wave form,then the very same answer would be correct.

Quote

 current?

Not if they know what they are looking at,which was the very reason i asked minnie the question--to find out if he had the skill set/the right to say i needed to learn basic induction.

This is exactly what i mean by !!adding confusion!! to add something that is not related to the question asked in regards to the scope shot.

Good, thank you for acknowledging that.

For future reference, I strongly encourage you to note scope channel inversions or coil lead flips on your diagrams and/or descriptions, regardless of the purpose of the post.

As you will see(in most cases),i do exactly that. But if i had done that in this case,then the question is already half answered for the person asked.

Anyway,have you had any more thought toward the effect being seen in my little experiment?.

I in no way can see the change in impedance being the cause for the drop in current(power-as voltage to primary is fixed)to the primary coil. I have used what i know to determine this,and so that is why i asked you the question regarding-what can change the impedance of a transformer,as there may be something i have over looked,or do not know about.
I do not count a CEMF from the secondary reducing primary current as an impedance change,as in most cases,an increase in secondary current would result in an increase in primary current.

Due to the fact that we have a decrease in primary current as we get an increase in secondary current,then a change in transformer impedance would mean some sort of positive outcome impedance increase on the primary,where it has the opposite effect we would think it should have.--what ever that means?,and hence my request for some information.

   I haven't got much interest in the circuit, the point I was trying to make was
   understanding the very basics of magnetism and induction. Lorentz and Einstein
   and that sort of stuff.
      You have to accept a lot of that to be right,study "The Moving Magnet and Conductor Problem"
   can be found on Wiki.
      It's got to be a bit of a joke all this argumentation over a transformer where you
   have dots to show the way
       Otherwise fritter and waste your life away sniping at MH.

I would be seeing what polarity emf is induced in both the secondary and primary from the magnet motion alone (you've probably already done that). I'd also be attempting to determine all the phasing and timing, as MH suggested, in order to try and piece together what is happening throughout the process.

Do you think the same effect would be present if your air transformer was just a simple 1:1 ratio? Have you tried it?

I am doing what i can,as i can.
I have the laser setup for the timing relationship test. But at a guess,i would think the timing of the magnet is 90* advanced from that of the current(magnetic field) of the primary,due to primary and secondary phase alignment with the oscillating magnet in play.

I feel that the magnet is not having a primary effect on the primary coil,but a secondary effect arising from the increase in current flow in the secondary,and where the magnets primary induction relationship is with the secondary winding.
So we have a situation where the primary coil is driving the oscillating magnet,and the oscillating magnet is the provider for the increase in the secondaries current /power output. But due to the magnetic field phase relationship between the fixed field orientation of the PM,and that of the alternating field of the primary,some how is allowing the secondaries EMF/current phase to line up with that of the primaries phase.

Anyway--a bit of guessing going on,in way of observation of scope shot's.
Will know more soon.
In the mean time,do you know of any other way that the impedance could be changed,where it would not work against current understandings.?.

How about my 1:1 transformer question?

Oh yea--sorry.
I will wind a coil tomorrow with the 1:1 turn ratio,and will give it a go.

I have just shortened the oscillator stem,and managed to increase the resonant frequency to-close to 40Hz. This small increase has made a big difference in the secondaries output,as well as lowering the primaries P/in even further. After some experimenting with the frequency,by adjusting the frequency .01Hz at a time either side of the absolute resonant frequency,i can actually get the secondaries current to lead that of the primaries current,or if i adjust the frequency the other way,i can get the secondaries current to lag the primaries current.

Have you ever seen a transformer where the secondaries current leads that of the primaries?.

Preliminary power measurements.

Without oscillator setup.
P/in 173mW
P/out--5 ohm resistor across secondary= 320 uW-.32mW

With oscillator in play
P/in 147mW
P/out--5ohm resistor across secondary= 7.372mW

That is a 15% decrease in P/in,and a 2300%+ rise in electrical output,as i will be leaving dissipated energy by way of vibrations out of the mix--to hard to measure.

Well, going from 0.18% efficiency to 5.01% efficiency is progress no doubt.  Doctor Strangelove would be impressed.

Another idiotic comment from the peanut gallery.
No idea at all as to how the transformer is wound,what the turn ratio's are--and so on and so on.
Also pays no attention to details regarding rasing the inductance value far beyond that of what the PM could.
How are those answers coming along MH-- Wouldnt want you in the same boat as EMJ--now would we.


3rd  time asking MH 5 questions about transformer impedance.
Oh,and here is a new one MH.
Question 6--provide a link or information on a transformer where the secondaries current leads that of the primaries current.
I will add that one to the list MH.

1-The drop in current flow through the primary coil(the drop in P/in),means the impedance value of the primary coil went up or down?
2-The increase in current flow through the secondary coil,resulting in a higher power value dissipated across the 5 ohm resistor, means the impedance in the secondary coil went up or down?
3- The combined results of the transformer as a whole,means the impedance went up or down?.
4-The phase relationship between the primary and secondary coils current is bought into phase with each other how?
5-Show another transformer test carried out that shows the EMF and current phase relationship between the primary and secondary coil of a transformer to be in phase.
6--provide a link or information on a transformer where the secondaries current leads that of the primaries current.


Lets hope you dont fail like minnie did ,with what you deem !simple questions!
