This thread will be continued, I'm building the contraption right now and run some tests to find the answer. I will post results and video material, I still could not find a simple and satisfactory answer for that question on internet.

QuoteMy Only Question Is :
      -  If you have a  'Free-Spinning-Disc-Magnet' on a shaft,  and then you bring a  'Straight-Wire-Carrying-Non-Pulsed-DC-Current'  near( but not touching ) to one-half of the 'Disc-Magnet'( OR, to the surface of the outer-edge of the 'Disc-Magnet' ),  WILL IT CAUSE THE 'DISC-MAGNET' TO SPIN  ?

magnet wont spin , it will experience a force but no rotation.

no one answered my question, that was:  homopolar generator produce steady DC current ??(no emf near disk) what about rpm changing? its hard to have constant rpm.. voltage fluctuates? or not?

No it will not spin.  It will turn to align with the magnetic field around the wire and then stop.  Try it with a compass and a piece of wire.  Use a resistor to limit the current through the wire and hold it over a compass.  When you energize the wire the compass will turn to align with the magnetic field of the wire,  but then it will stop.

    Thats what I assume,  and sounds correct.

    (  I assume the result would be exactly the same if the wire was put near the outer-rim of the Disk-Magnet,  as in the diagram below ,   I'm sure the result would be the same.   )

   
Quoteno one answered my question, that was:  homopolar generator produce steady DC current ??(no emf near disk) what about rpm changing? its hard to have constant rpm.. voltage fluctuates? or not?

    The only thing I can think of( vaguely-related ) is the ' Electron-Microscope-Research a while ago,  using a special method to view the behavior of magnetic-fields on the surfaces of magnets,   which showed that the  magnetic-field  forms tiny vortices ( magnetic-tubes, tornados ) near the surface of the magnet and they react and interact in all sorts of interesting ways.
     I mention it,  because I assume that that PROVES,  that when you SPIN the Disk-Magnet,  that the Magnetic-Field moves with the Disk-Magnet(  that the magnetic-field is not just a cloud around the magnet ). 
     (  The above also made me wonder,   if there is a way to spin the Disk-Magnet in my question,  and while also suspending/floating  the disk-magnet in a  permanent-magnet-only-bearing ,  since some people on this site claimed to have accomplished  magnetic-levitation using only permanent-magnets )

    I don't think the Disk-Magnet would turn at all,  because unlike a compass-needle,  the Disk-Magnet would have no reason to turn clockwise or anti-clockwise.

PolaczekCebulaczek and all HI !!

Let's start from the very begining.

Prime question is: "Does the test electrostatic charge and a magnet interact among themselves ??".

Experimental setup:

Take a glass tube. Clean it from greased sweaty hands with alcohol. Now rub one end of a glass tube with synthetic fabric, and suspend it for the middle by means of a rubber flagella to a rack and bring at in vicinity permanent magnet near the polished end of glass tube.

1. Is there exist any ineraction of electrostatic charge with proximity of southern or northern magnet poles ??

Now do the same, but with not the polished end.

2. Any interaction ??


To undesrtand any electro-magnetic paradox it was quite necessary to understand on prime experiment does the electrostatic test charge and a magnet interact among themselves ??

ps: the Saga will continue !!  :D

magnetically there is none, but charges would stick to magnet's metal, no matter what pole is facing glass.(I tried something similar with paper).
