WARNING Cant believe what im reading

Also
Some ring magnets have multiple poles on their faces
even when they appear to be a solid piece


Sometimes this is intentional, like those found in floppy disk drives
Other times this can be caused from use
such as those pulled from a used microwave magnetron
or during manufacturing, due to cheaper processes of magnetization.

I can go with that. The noise shown in the vid when just the magnet spins is probably showing those inconsistencies in the disk/ring magnet itself. Nothing is perfect.

The ones that are cut/sliced from cylinders also can have inconsistencies
There are some that are closer to perfection
They are generally more expensive, made from an isostatic press magnetization


The most common (cheap) magnets are sintered, then magnetized with a solenoid
These are generally less consistent.

What would happen if you take a strong neo ring magnet and stick it to a iron disc and have that iron disc facing the copper disc?  Would it even out the magnetic field ? Would it even work?


Second:


About Tesla.  Tesla seems to he stated once that off all his inventions the tesla turbine was his best.   I  often wonder about that statement because i think we are missing something about the Tesla turbine. It's a nice invention, but to call it his best?


Unless...


We only know half of it's capabilities..  I think. I think some of the functionalities are being left out...  for example


A. What if the Tesla Turbine was constructed to function as a static generator?  Those multiple high speed rotating plates can with a little engineering deliver some nifty sparks !!


B. What if the Tesla Turbine was constructed to function as a homo polar generator?    Just alternate the discs with copper and magnetized plates...  stack them as normal...  rotating as a normal and... voila !   Muchos Powerrrr!

One of The Godfather's of particle acceleration created a 7ft homopolar motor
the magnet was electromagnet that was only switched on after the giant copper
disk was spun up.


The sliding-contacts were made of liquid metal alloy.
Sodium-Potassium (NaK)
We can get it from inside old 2-wire thermostats
Like in an old oven or A/C thermostats
Be careful it explodes with moist air or water


Mercury may be safer, but has its own dangers.




Iron:: 
I see this as basically weakening the magnetic field, and also producing its own
Eddy currents. But otherwise should still 'function'.

I'm not sure if this has been answered, but I just satisfied myself that there is indeed a massive drag force on the rotation of the homo-polar disk, whether with co-moving magnet or not. If the current flows from edge to disk centre, as it will do in the generator if the field is downwards and the rotation CCW, then the Lorentz force on the current is CW. I.e. the Lorentz force acts a la Lenz's law to oppose the movement giving rise to the current.

The more current drawn the greater the drag force and so the more input mechanical energy is needed to keep rotating at constant speed.

So Aaron is indeed wrong to maintain that there is no drag. This is certainly no OU machine.
