Ultimate proof of Magnetic Vortex, free book and videos

Regarding dual homopolar counter-rotating plates.  He has to have the current going opposite directions.  If you put another magnet aligned the same direction near the bottom, the field would still be the same direction as the top.... he has to have the current running something like....

Yes, this appears to be correct.  My sincerest apologies TinMan!

Tinman,

Regarding your "bubble vortex" video and experiments:

It may be informative to repeat your test using a neo wrapped in electrical tape.  Simply wrap the tape around the magnet leaving only the very poles exposed (i.e., insulate the sides from the electrolyte).  See if you still have a bubble vortex under similar conditions to your previous test.

You could first verify that you can generate the vortex with the magnet prior to applying the tape, and then apply the tape to that same magnet and note any observed differences. 

I know your time is valuable, so consider this just a suggestion,

Thanks,

Yes, either what you proposed above for the PM or wrapping the EM in aluminium foil.  This needs to be ruled out.  In a HPM, the torque is not on the magnet itself and the magnet will only rotate if it's attached/glued to the copper disc.  Hopefully I can get my magnets back from my ex g/f and do some experiments myself, lol.  This is not the first time she has held my magnets hostage, lol!

If there is a vortex in a PM and not in an EM, then this can lead to some very interesting experiments in a HPM / HPG!

test done,and video uploading to youtube now. But before i post it PW,what do you think the outcome may be?.

What i need is a big 2 or 3 inch neo to do these test with-that would look awsome. But as per usual,i cant get one that size here in OZ-all out of stock apparently lol.

Tinman,

I am speculating that you will find that the torque that spins your neo in the liquid homopolar motor video is also present in the bubble vortex video.  But, in the bubble vortex video, because the neo is stationary, the torque instead imparts a spin to the electrolyte, producing the observed vortex (A colored marker taped to a dowel and slowly dipped into your tank to approach the neo should allow you to see any spin imparted to the electrolyte).

Also, because the electromagnet has limited current flow through the electrolyte perpendicular to its magnetic axis, little torque is generated with which to stir the electrolyte, hence no vortex.

If this is correct, taping the sides of the neo should reduce the current flow perpendicular to the neo's magnetic axis, reducing or eliminating the torque/electrolyte spin and vortex.

Thanks for taking the time,

PW
