Magnetic braking of magnets sliding along a sloped aluminum surface

[BEP]

Are you aware of any books, papers, or websites that discuss this behavior?

Nothing on the web. I've only been using the web for such activities for about three years (still don't trust most web sources). It could be there buried in a thesis somewhere. I don't know.
Books? Yes. The first time I saw related issues was in a late 40's CQ or QST relating to antenna design difficulties when using Al instead of Cu. I remember reading about a maglev train that hit the rollers above a certain speed and all the brains freaked out with no answer. Don't remember the article but it was in "2000" (?) A former science magazine for the masses. The main thing I remember was my feeling - Yea DUH! what did you idiots think would happen?

My first experiments were with transformers. I was trying to see why the primary and secondary were out of phase by a 'none book' amount. Make an Al core then things really go wacky!

At the moment, I think this is the most rational explanation we have.

Not something said about a comment from me before. Make sure you are ready to withdraw that comment should the torches head your way 

But I still have some questions:

1) As TK mentioned, these speeds are far from relativistic. Why would the oppositional field created by the eddy current lead or lag the magnet?

2) Why would polarity make a difference (unless there is some external influence)?

Still wondering what TK's upsliding experiment will show us.

I have answers for you but I'll basque in your earlier comment about my statement for a while first....

Nah! that'll really throw the thread of course.

Due to the shit storm it's hard to get some constructive things out of this thread.

Has it been established that the flip is caused by some repulsion of the aluminum? This could lead to some interesting technical discoveries.

@tk what's with the rotation video? that's more old news you know...
but go on with your bad self. from your vid clip: "should i repeat it?" yeah yeah, you better. this is big news!!


oh goody, look there's a video from 2006... well that's that then, someone HAS done this before, there is video proof even.

the rotation is obvious. no audio, sorry. the prof. demonstrating it isn't quite as interested in hearing himself talk as you are tk. he keeps messing with the magnet, but the rotation is there none the less.

so again, if you can't put two and two together and deduce what comes next or even be bothered to observe the experiment when shown to you in college, you aren't as creative, imaginative, deductive or logical as you think you are.

p.s. still waiting for your debunking of stiffler. you got 50 years of experience and scorched fingertips to boot according to your own claims, should be a walk in the park for you to show how stiffler is conning us all. it sure wouldn't cost you $900 and 80 hours of your time like this magnet stuff. oh yeah that's right your concentrating on the, how did you say it to me? "concentrating on the easy stuff: gravity wheels, magnet motors, and buoyancy drives (and you can see how hard it is even with these obvious losers)"
that's funny, that you like playing with these "obvious losers", so nice of you to say that about them too.

@ WilbyInebriated
I feel it is obvious that you have not had a real or a original thought ever in your life, because if you had you would know that cooling a material with liquid nitrogen would most likely make it a super conductor, which I would hope that most people on this thread would know that the reaction of a magnet to a super conductor, and the reaction of a moving magnet and aluminum or copper or brass ect.... is completely different. Or just maybe you have been stuck in your mom's basement for to long.

Broli, in my tests I have tested 6061 aluminum, 7075 aluminum, copper busbar alloy, deoxygenated copper (vacuum copper), naval brass, leaded brass, copper busbar w/ thin silver electroplating, and al-clad.
The nature of the effect is the same in all cases, but the magnitude and the critical angles, as it were, are different, using the same magnets. Different magnets...I dunno. There are alot of variables.
One thing that I haven't tested is copperclad g10 circuit board material. That's today.
One thing that does seem to make a little difference is the cladding or plating.

Did you also test on thicknes? Maybe using some thin smooth aluminum cooking foil on some plywood.
