Magnetic braking of magnets sliding along a sloped aluminum surface

[mikestocks2006]

I tried it with my big rectangular ceramics. They do it too, but they are kind of hard to slide stably. But they do it.

And the leading edge thing--I only observed it with a very thin disk --think US Dime --on a big thick Al plate. I can't seem to get it to do it (lift up on the leading edge first) with any of these more cylindrical or square magnets.

TK thanks for testing/answering. Glad to see lostcauses10x  bring it up again.
That same question was asked right after lumen's post of the phenomenon.

@TK
I posted a short video showing the uneven magnetic drag effect with a few different magnets. I am sure it is there but don't really know why at this time.

It's almost like one field direction has almost a hooking effect on the aluminum where the other direction a light push.

Hi lumen,
Could you quickly try the same experiment with nonconductively coated magnets? Curious if there is a "skin effect" due to the typical electircally conductive Nickel coating over the Neos, and its interaction due to eddies etc.

Nice interesting observation, thanks for posting.

Now regarding the repulsion effect, at sufficient relative speed, it does seem to work.
This maybe of interest as a demonstration of the repulsion effect, at speeds of up to 24 mph maybe even less.

TK, as the mags accelerate towards the lower end of the Al or Copper surface, is there an estimate on how fast they are traveling at the time they start moving away/flipping??

Thanks
Mike

It almost makes me believe in different pole strengths.

C'mon now. That wouldn't be symmetrical, would it?

@ all, i confirm TKs claim that the neo "flips backwards" while falling, very odd. It also interests me if this happens on the bottom half of the planet, like flushing the toilet?, water spins opposit in N. vs S. hemispere, neat stuff. We nead south of the border neo input!!

You are speaking of the Coriolis force which is a myth, but an understandably created myth, I believed it most of my life.

In this case, I think the purpose of the experiment would be to see whether the earth's magnetic poles influence the magnet's behavior. If he N pole flips in the northern hemisphere, does the S pole do it in the southern hemisphere?
