Constant flux DC motor/generator.

Nice videos also, but still both of these have already confined fields.
Think of the first with the horseshoe magnet, along the direction of travel, the field has a start and end. These are the confining boundaries.
When current is moving through the conductor, more of the force lines are moved to one side of the conductor. This is what causes the force to be exerted on the conductor.

In Broli's circular path, there is no start or end, so the field is not confined.
When current pases through Broli"s conductor, it will cause a void on one side and a compression on the other side which should make it move. Instead it is much easier for all the lines to just shift around the circle to fill the void.

I wish it were not true because it would solve many problems, but that is exactly what will happen.
This is the entire mystery of the homopolar motor and generator, that seems to baffle everyone.

Everyone including you it seems. Here's a good place that will re-adjust your knowledge

Also where are these numerous experiments you have apperently performed. Somewhere up in a cloud maybe? Atleast post your failures and succes so we can all learn and talk about it, that's the point of this forum.

Sorry if I sound rude but your compression and decompression theory sounds like complete baloney to me. I look at the source of the magnetic field being the material and its interaction with moving charge while you are hooked to the imaginary field lines physics book draw to present a magnet and its behavior. From my standpoint a homopolar motor is as clear as a sunny sky. Just analyze the source and the moving charge and you can get all the forces you need. You will always find that the biggest force interaction will be at the places where the charge and magnet source are closest to each other. This follows from the 1/r^x rule.

Your knowledge says a moving charge in a magnetic field causes a force.

My knowledge says a moving charge generates a magnetic field that can act upon another field and may generate a force if some conditions are met.
I don't know how you can just say it must work when you do not first examine exactly how it will work. You cannot use a standard law and expect it to work in anything but the standard cases.

Why do you think everybody building a magnet motor sees a working principal, but once they close the circular loop, it no longer works?

It's because field will shift around a circle once the ends are gone to contain the field.
I understand what you are saying, it is complicated and you will not be convinced unless you test this yourself.
This is not a common situation, the problem I am describing ONLY exists on a circular homopolar device where the field is of constant density and direction along the path of the conductor.

The spinning magnet, the spinning disk, the spinning conductor, it all relates to the same thing!

I have done many experiments, the one I am doing now is forcing a conductive liquid through a strong magnetic field and testing for a voltage. I must say this is puzzling. NO detectable voltage!

But there should be, so what is wrong? The fluid is very conductive with magnesium sulfate and will electrolyze if a current is applied. Still testing.....

There was more to this post, but it was removed, the remainder was a warning, it's now been 'clarified'....

@all,

It should be noted that both gallium and mercury are very poisonous.  In those experiments, it was found that eddy currents were more prevalent in the liquid conductors than in the rotating disk.  I remember reading one such setup where Mercury was used AS the rotating disk... and very little current or voltage was produced.  It was a vortex of sorts...

Gallium could be used similarly; it seems to have higher melting point.  I think it may be interesting to see the results of a disk of solidified gallium used as a Faraday disk.

...This thread, in general. isn't too much different from the hpg / lenz thread.  I'll transpose a thought from there...

The problem here is that, in order to take off the current, you have to create a path between the axis of rotation and the rim of the disk.  This cannot rotate with the disk, or no current is produced.  It is therefore logical, that it is the radial path which is where the current is being generated.

In such a radius, the rotational speed ( in surface feet per minute ) is least near the center and greatest near the periphery.  THIS is where the change is occurring; the path's inner atoms are spinning slower than the path of the outer atoms.

And yes, eddy currents play a part in this; but it is the relativity which creates the apparition of a changing magnetic flux.  Even though the field strength is the same, it is as if to say that there is one end of a wire moving faster than the other in an even field; therefore there is an affective difference experienced in the wire.

What would generate more current?  [ in an even magnetic field ] A wire of a given distance moving at a given speed, or the that same wire of a given distance moving at three times that speed?

It's really all about what the individual atoms are experiencing [ and thus ] contributing as a whole.

When a vortex is used, the notion of the speed of atomic translation is nearly inverted, ...with the speed on the inside moving faster than the outside relative to the axis of rotation.

A continuous current motor, I believe a possibility; I have been working on one myself, but the contacts are shoddy, and any results I've come up with have most likely been the result of periodic disconnecting from the contact, or some other phenomenon associated with wobble.

I sure hope this was posted in the wrong thread by accident.  This is totally off-topic and a total distraction to this thread.  I sent you a PM about this.
