Howard Johnson Replication Tube Claim

TK:

My understanding is that the south pole of a magnet is the one that points to the north....you know, opposites attract.  I believe this is the generally accepted method of labeling them.  If you use a compass, the pole that attracts the north facing dial is the south pole.

Al, will you kindly lay out the specifics of your theory instead of making cryptic comments. Tyvm.

I simply cannot believe that TK does not own a $25 pole finder. The world is spinning in the wrong direction, I want to get off.

Here is a theory

South pole sliding down, may be causing an attracting force from the aluminum, and vice verse.
But my guess would be doing a rundown for each pole facing the aluminum, should be the same drag either way.
But, what will be very interesting is to measure the attraction and the repulsion by the different poles.
Maybe have the magnet in a tube dangling from a loose spring and I bet the magnet lowers or rises depending on the pole that is facing the moving rotor.

Wutcha think TK?

Edited for stupidity

I believe that there is no attraction in eddie current. The eddie current in the aluminum or copper will only create the exact pole that is facing it.
As for my thought on what is happening is that you guys have physically proved that one pole is stronger than the other. The weaker pole is not strong enough to make enough eddie currents to slow the fall. I think?

Nice demo TK, now you got me looking for copper or aluminum do to this experiment, it really is a curiosity, it's as though during travel eddy currents only happen in one direction despite magnetic pole orientation, the side that falls off the fastest appears to be repulsed away.

I just made a little video of my replication of this phenomenon. Thanks, lumen and x00000000013 for drawing my attention to it. I don't have any idea why it does this.

Pretty dang cool.
Can you see the fishing line? 

And I'll be doing the other suggested eddy test on the wheel in a few hours.

(Oh, and this topic definitely deserves its own thread...)
