Unipolar Induction - Relative motion isn't needed!

[lumen]

The topic of this thread, in case you didn't notice, is relative motion isn't needed, nor is it a requirement for induction.  As Broli already posted, Prof Muller shows that you don't need a "stationary" circuit piece in order to generate a voltage.  The other experiment shows that a voltage can be generated on the classical "disc" of a homopolar generator by spinning the magnet clockwise and counter clockwise in an oscillating matter, showing the acceleration and deceleration being the cause of voltage generation.  This experiment shows you don't need a "rotating" circuit piece to generate a voltage.  The two experiments shows there can be induction without having relative motion between a stationary circuit and a rotating circuit.  In other-words, a rotating magnet with a constant rotational velocity (RPM),of any value, will have the same effect as a stationary magnet which has a constant rotational velocity of 0 RPM (both cases are the same thing), since they both will have a non-varying RPM).  However, a rotating magnet varying in RPM (acceleration/deceleration) as compared to a magnet with a non-varying RPM, including a magnet with a non-varying RPM of 0 (stationary magnet),  will not produce the same results (both cases are not the same thing).

Well I must say, I'm certainly no Professor!.
I do agree that a voltage IS generated during acceleration and deceleration, OR anytime during rotation, and with only a single pole piece.
It's just too bad that everything goes to crap as soon as you try to generate any CURRENT!


Have at it!
But please, you be sure to let me know though, next time the boat comes in.

You missed the boat again!  You now agree that a voltage is generated during acceleration and deceleration (OR anytime during rotation) of a rotating magnet with everything else being stationary?  This statement is not inline with the first 120 seconds of your own video, HPG02, showing a rotating magnet produces no voltage regardless if it's shielded or not.  You care to explain this contradiction between the statement you just made and the video you produced.  You do realize when I say an accelerating/decelerating (oscillating) magnet induces a voltage that there is no co-rotating disc or rotating circuit involved?  It appears you have been reading this whole thread out-of-context, or should I say skipping most of the posts and references cited in this thread, just as Vidar admitted in doing.

I understand how frustrating it becomes when something not well understood is held as a hope for a new energy source only to find it isn't. I thought of oscillating the magnets, the disk, a wire, anything to avoid brush contact and back emf, but it's all to no avail. Back EMF will exist anytime a CURRENT flows, and without current no work can be done.

Any conductor moving in a magnetic field will experience charge separation and is not news, but to test for charge separation is a trick in itself. In any of my videos I do not even attempt to show this charge separation because it is extremely difficult and because it is of no use without current. So in my videos, the voltage is only registered because it has current.

Even Einstein did not fully understand the aspects of the Homopolar generator.
I believe I fully understand how and why it works but continue to read these threads trying to find something I may have missed but so far have not.
The best thing is to verify for yourself the results given in the first post, fig #1 and #2. You can rotate any conductor in Earths magnetic field alone and have charge separation but to simply translate it and produce a charge is something different again. Did the Professor even take into account Earths field? There is no way to know without duplication.

If you think something here is out of the ordinary, then continue on, I'll check back later on your developments.

I too agree that Lumen missed the boat, but at the end of the day it comes down to one thing, experimentation all the rest is meaningless.

Anyway I got so curious about that "the yoke never moved" statement that I sent an email to Prof Francisco J. Muller about it:

Dear Prof Francisco J. Muller,

I have been fascinated for a while in the subject and physics of the classical homopolar motor. My research has led me across many areas and I have learned so many things on the subject.
However the more depth I gained on the subject the more I realized how little this subject has been explored across history let alone in todays academic establishments.
I fell upon a lot of paradoxical experiments across the years that really piked my interest. These involved either a generator that has no stationary circuit parts or a motor that has no moving circuit parts. Your experiment is a good example of the former.

To cut this email short I actually mainly contacted you because I had one specific question. It concerns the paper you wrote; "AN EXPERIMENTAL DISPROOF OF SPECIAL RELATIVITY THEORY (Unipolar Induction)".
In the paper you performed a very interesting experiment, where you confined the field and saw an induced E when you rotated the whole circuit together with the magnet assembly. My question is this:

Somewhere in the paper you mentioned, in my opinion, a very important fact. I quote "The yoke PP' never moved". After reading this paper I was left with one very piercing thought, namely; What if the the whole circuit, the magnet assembly AND the yoke were all moved together, would this scenario stlll induce a voltage???

If it doesn't then this sure would be an very interesting fact as I predict that the very motion of the yoke relative to the circuit to be the main cause of induction, opening up a new paradox. However if it does induce a voltage then I'm sure you can realize the implications this might have; it would open doors to a truly torque-free electrical generator. As the whole assembly can be rotated as one, canceling out any torque in accordance to Newton's third law.

I will be eagerly awaiting any answer from you so I will thank you in advance for your time.

Best Regards,
Najib

Let's see what the prof has to say ay :p.

I wish I did miss the boat on this, but I suspect that if "the yoke PP" were to rotate with everything else, the voltage would be gone. (can anyone say second conductor)
After all, if everything rotates, then it's the same as everything sitting still and you rotating, which we are so it should produce a voltage all the time as the earth rotates!

That brings up the basic problem of this concept. How do you check the charge in the single conductor without the testing method altering the results?
