Just a comment on Brad's post #1807.

I said, "As I alluded to before, the "phase shift" is not even real - there is no phase shift. It's just an abstraction we use to make it easier to describe sinusoidal-type waveforms you see on your scope display."

Brad thinks this is really funny and makes a long posting mocking me for several times where I mention "phase shift" in my postings.

Read again, "As I alluded to before, the "phase shift" is not even real - there is no phase shift. It's just an abstraction we use to make it easier to describe sinusoidal-type waveforms you see on your scope display."

I am clearly stating that the term is in use and I clearly have no problem with it because I use it myself.  The point being that if you scope the current through the primary of a transformer and then look at the open circuit voltage on the secondary, the voltage on the secondary is instantaneous relative to the "excitation signal" of the current in the primary and happening in real time.  There is no true "phase shift" if you interpret "phase shift" as meaning "shifted in time."  We only describe the voltage output on the secondary as "appearing to be shifted in time" but in fact the output is an instantaneous output and not shifted in time.

That's just a subtlety that I wanted to mention because I thought it might add some value to the PW/EMJ discussion.

Ah. I was thinking of the old modulus. ;) Im sure everything has elasticity by some measure.  But isnt it the tensile strength that determines that measure? Just of the top of my head here, not looking anything up on that. Yet. ;)

Mags

No, tensile strength is measured by pulling.  Then, there is torsional strength which is measured by twisting, and compressive strength measured by pushing together. Elasticity is the ability/property of a material to resist distortion under stress and to return to its original shape after that stress is no longer present.  That stress can come in the form of the above mentioned pulling, twisting and compressing or a combination thereof.

Ok. sounds right

I was thinking like this....

If we had a thin layer of carbon fiber strip, resin and cure. It would be a bit bendable as the thickness from side to side is thin.  The thicker the lairs become, the stiffer the strip will be due to the outside bend would need to stretch for the bend to occur. And the carbon doesnt want to stretch due to tensile strength. So higher freq.   But you are right. Carbon has very little elasticity, but still necessary for it to bend.

Hmm. just a thought.  If we had a 1/8in strip of layers of carbon fiber resin cured, it will bend, but very little before it breaks. Like glass or the wine glass.  So as we had seen in the vid, that wine glass had some crazy amount of distortion for glass, as we know it in normal life. So, maybe that 1/8in carbon strip would also bend a lot further when bending at say its resonant freq before breaking.  If so, could we say that at resonance we can enhance elasticity? It would certainly seem so with the wine glass. Just try to physically distort it that much at any freq other than the resonant freq. I wonder if the wine glass gets warm oscillating like that?

Wrong again.

There is such thing as phase shift,and i gave you pacific meanings for the term phase shif-which happens to fit perfectly with  transformer voltage and curret relationships.

You need some schooling MH- truly you do.
More garbage from you in order to cause incorrect understandings of simple actions.

You are going to play the wrong again game again when you are wrong again?

Yes indeed, a signal can truly be phase shifted and truly displaced in time by things like delay lines and other stuff.  In the digital domain it can be done with shift registers.  In the ancient computer days it was done with a long horizontal tube half-filled with mercury.  Or if the same signal travels through one meter of coax and 20 kilometers of coax, then there will be a phase shift between the two signals where they are truly displaced in time relative to one another.

But when you look at the secondary output of the transformer as compared to the primary current when the primary current is a sinusoidal waveform, then the secondary signal is not displaced in time.  If the primary current waveform is a sine wave then the secondary voltage waveform will be an instantaneous cosine wave.  They are not displaced in time at all, they are just different waveforms where it is convenient to say that they are "phase shifted" relative to each other.

All that I am saying is that there are two meanings for "phase shift" but like the brutal abrasive wanker you are, you have another good wank and say that I am "wrong again."   Between the two postings I made about this topic I suggest that you reread both of them enough times so that it sinks in and you understand what I am saying.

I think that you have to bounce it back and forth.
Thanks for the video , To me it shows only a quarter of the wave?
artv

Tinman, I want to apologize for this post ,I made it without viewing the whole video. I was interrupted by a surprise visit from the grand kids.
Thank-you for the demo it seems the most drastic change occurs just between in front of TDC and just after.
My current setup is 2 horizontal magnet rotors spaced apart to allow me to insert a coil. Also when the coil is in place the lower rotor has a north pole magnet centered on one side of the coil, while the upper rotor is a north pole centered over the other side of the coil.(eliminates the drag effect)
Do you think this will still be the same wave form?
Thanks artv

Well i can see that you did not agree to Bills request to stop with the vulgarity--you really are a disgusting old man. You really do turn into something else when you are wrong.

This is what i mean--your limited understanding regarding phase,and what it is.
There dose not have to be an overall time difference for each cycle for one thing to be out of phase with another. You need to go back to basics MH--perhaps review two children swinging on two swings of the same kind,but where one child starts swinging first,and the second starts when the first has reached the point of 1/2 a cycle. The child that started his swing first will always be say 2 seconds in front,and there phase can be said to be 180* out,but where there cycle time is still the same for each cycle. When the first child stops swinging at his starting point,the second child will not reach that point for another two second,but still there cycle were  exactly the same.

You say there is no time difference,and so there is no real phase shift--well that is just plain wrong--incorrect MH--try again.

P.S--Is minnie your son?--just asking :D

Lol-again minnie ;D ::)
All you have to do now,is find something in this thread that i was wrong about.
As you have admitted to not having a clue,how will you know i was wrong when you find it?.
No point in asking daddy(MH),as he has got almost everything wrong in this thread--he even managed to balls up his resonant wine glass fiasco that we all waited 4 to 8 weeks for :D
I was actually expecting something good,but it was a big let down when i read his answer's,and it seems so for most everyone else here on this thread.

It's all good to say some one dosnt have a clue,but you have to back up your claim--as i have with MHs mistakes in this thread.

With a single magnet like in the setup,where the field is very concentrated ,then yes,we will see very sharp rises and falls in the wave form. If we have a rotor with nice wide fields with even transitions,then we will get a nice AC wave form.

Do you think this will still be the same wave form?

If your coil is nice and evenly wound,and your magnets are of the same size and strength,and pass the coil at the same speed and at the same distance away from the coil,then there will be no wave form --no EMF will be produced across the coil.

Dear Bill.

How many more posts are you going to tolerate with the obscene language ?

All should remember that OU. Com is open to all ages, my grandchildren look in from time to time because their " wacky " grandad posts occasionally.

I'm sure dear Groundloop would have stepped in a lot sooner!

I'm no prude but...... Enough is enough.

Kind regards, Grum.

@MH

You have no damn clue of what I am talking about yet you have the gal to call it "spintronics magic". So let me see Mr. Reality KnowitAll, provide these 5 simple requirements.

1) Prove to me a magnetic field exists.
2) Prove to me field collapse exists.
3) Prove to me electron flow exists.
4) Prove to me current flow exists.
5) Prove to me flux exists.

So how long or better still how many lifetimes will you need to prove these. But realize that proof has to be irrefutable. So go ahead BigMan with a big stick ready to push it on any who does not concord to your learned illusions of effects. hahaha

Your hell hole is so well furnished you think it's actually a home. It has all the trimmings, all the excuses you have digested and now think is reality is actually a base of illogical constructs that have been sold to you via those "authorities" that you consider to be equal to your own religion. You have sucked it all up and then closed the most important part of your brain, the part that thinks.

It is your Standard EE that is on a partial pass for now. But that pass it about to terminate and soon you will be seeing something that your little brain will not be able to cope with. Truth. Truth that will then confound your existence because you will then realize that all these years you, (even my Dad) and anyone else in the EE spectrum has been sold a bill of lies. Oh the lies work indeed but they were designed to keep us stupid to the real facts. Blind but functional, that's what your EE is today.

So keep sucking on your field and keep encouraging all those electrons to move in that one direction and keep believing that what you are trying to teach is actually real. hahahahaha

But before you take EE to the bank, maybe you should study for yourself how your EE formulas were derived. What brain power was used by the men of those days. What preconceptions were used to become a base of observation of their effects. Of the 5 above, none were left out. All UNPROVEN but all used in every single formula EE has to offer. So what do you say about a science that bases its concepts on so much presumption, yet you treat is more factual then your own life.

You got sucked in. We got sucked in. They got sucked in but all think life is grand. So how many more generations do you want to preserve this illusion we call knowledge. Knowledge of what. Knowledge of lies.

What I am doing now is mountains harder then anything you have ever done. You just keep drinking your EE Kool-Aid and keep thinking you know what our reality is. You have the same lazy mind that only looks to turn to a page in your book, because if it is in your book, it has to be real. You have zero ability to question your truths but that is inbred laziness of the mind because the basic observations have always been right in front of your nose. You just can't see it because your eyes are trained to disregard the same concepts that have been paying for your livelihood for so long. You got paid to dream.

This is supposed to be an OU forum destined to accomplish or design devices producing OU. This will never come from the EE constructs. Nothing in EE will ever bring us closer to OU. It will only distract us and push us further down into a hole of continuous illusions and you are just the perfect vector to keep the hole deep and slippery.

The HCS I put forward was a test. A test to see how sick the EE patients really are. With this one simple observation and your remarks, this is just standard. So show me your bench that proves HCS is wrong. Such a simple effect. Just prove this is wrong. What? Oh I forgot you never do bench work. You only talk and insult your way to push your EE Kool-Aid like a drug pusher. So that is your forté.

Nice model. You take your present construct that has no proof of anything real and you flog this to the masses that work towards OU. F you man. You are the sick one. Don't ever talk to me again. You are just bad news for any OUers alive.
