Ah, that's only magnetic bearing. The small magnet sits in the hole of the magnetic field of the big ring magnet? Quite difficult to make any motor with that. And kind of useless too, that there is overunity can be shown much more easily. But a motor which barely rotates is more or less useless.

the value of using a magnetic bearing, would be to increase its lifespan when compared to a not so magnetic bearing due to friction.
also the lack of friction means the bearing can essentially run using less power input.

as a example, a vertical axis wind turbine/windmill.

this floating bearing system can possibly be used for many other ideas.
such as a near frictionless axle that might be used in the development of a maybe possible overunity device, though the bearing will not be the reason it keeps running on its own.
there is the risk that if there is cogging that might occur in the design, to cause the floating bearing to not remain in its exact position constantly, and this may be something of concern when working with such bearing systems mixed with other experiments.
though additional magnets might be used to counter act against the main bearings positional movement.
using anything else other than those additional magnets to correct that alignment would mean more material contact based friction.

though supercooling could help certain levitation of i think it involves bismuth or something else.
supercooling has its costs unless the generator itself can cover the extra needed energy for that cost, but that is getting beyond my scope of understanding which is easy to do when i try to make sense of concepts and theories, much flies way over my head, hats off to those it does not.

If anyone can explain,   completely correctly,   and using the simplest terms that  'anyone'  can understand,    what is the difference between an   Electric-Faraday-Motor  and a   Non-Electric-Faraday-Motor( which just uses 2 permanent magnets )   ?

Why would a   'Non-Electric-Faraday-Motor'   which uses 2   'pipe-shaped-bar-magnets'  set at  90-degrees from each other,  not produce propulsion  (  see the diagram in my earlier post ). 
    I would have thought that the reaction between these 2  permanent-magnets  would result in propulsion at a 45-degree angle.

(  What is the difference between a   magnetic-field   generated by an electrical current,  and the magnetic-field  of a permanent magnet   )

(  If your answer is that in the  'Electric-Faraday-Motor',  the  magnetic-field  of the permanent-magnet   also interacts with the  flowing-electrons,   then check the angle of that interaction  :     
-  when the electricity is switched to flow in one direction,    the  magnetic-field  of the permanent-magnet   is flowing in the  EXACT-SAME  direction that the   flowing-electrons  are travelling,  although assumedly at a different speed.
-  when the electricity is switched to flow in the  other direction,   the  magnetic-field  of the permanent-magnet   is flowing in the  EXACT-OPPOSITE  direction that the   flowing-electrons  are travelling                                      )

I am planning to do some experiments to determine why there is a difference.
I would have thought that because is conductor is non-magnetic the cross field does not interact with it, but I'm sure the Faraday motor would still work if the conductor was iron.

So maybe it's only because the magnet tube is not long enough to prevent the field simply entering the ends and preventing the effect. That's one thing I hope to test.

It could be that a conductor pushes the field outside of the conductor and a magnetic tube contains the field inside the tube so it does not deflect the cross field.

I thought possibly a spinning copper tube would deflect the cross field in a similar way and cause movement even though the rotating copper would require work.

There must be some reason why it does not work the same , right?

Guest1289, Lumen,

The difference i think is how the magnetic fields interact. In case of two magnets with the axis perpendicular, what happens is that the magnetic fields reshape, so that both poles of the rotor magnet shall be directly connected to the pole of the stator magnet. When the poles of the rotor magnet are at equal distances from the pole of the stator magnet, then the forces are in balance, and there will not be any movement. When they are at different distances, then there simply will be an attraction or repulsion radial to the pole of the stator magnet, again no movement. The same cannot happen when the magnetic field of the stator magnet is circular. I don't know every detail but, if you asked what is the difference, this is the difference.

I am getting some response that is something like what a conductor would do.

This is what I am using but the tube needs to be splined so the cylinders stay in alignment as shown. They now tend to lock together in the gaps when stacked and that appears to reduce the effect.

When placed over the top on a large cylinder magnet, the array wants to tilt like a conductor carrying current would do.
Once I devise a way to keep the orientation, I will try a few other tests to see if it's like a conductor.

No it seems not to be like a conductor with current but much closer to a single long magnet.
Though the magnets are diametric cylinders, somehow it has developed poles on the ends of the stack making more like a single cylinder magnet.
