Rare Earth Magnets and Giant Copper Pieces react

BILLIE MAYES IS ALIVE!!!!

[fannoj]

nothing rare about this.

[alphafirstoneyou]

i missed it the first time.

[alphafirstoneyou]

wtf? demonstrated nothing?

[TeslaCoilArbiter]

@alphafirstoneyou

you didnt notice how the magnet was cushioned when he pushed it over, and how the copper slab managed to slide around by him only waving the magnet over the top?

[DanFrederiksen]

it all boils down to fields being hard to understand :)

magic action at a distance.

reality is so bizarre if you start to think about it

[Krashulka]

drop a magnet though a copper tube , same effect , it slows right down dropping through the tube. cheers

[MrCensorman]

greater effect wit aluminum tube

[TEMPESTSPARK]

Look up Lenz's Law .

Lenz's Law states:

An electromagnetic field interacting with a conductor will generate electrical current that induces a counter magnetic field that opposes the magnetic field generating the current.

[rpm2004]

So this would work even better with a an ingot of silver because it's a better conductor? I'd like to see that though it would be an expensive experiment.

[rmariboe]

... and it will work perfectly (total diamagnetism) with a superconductor with no electrical loss and thus a constant, opposing magnetic field.

[Esternamornezz]

Cool, I've seen this magnetic induction work with Aluminum, but never saw it with copper, though I see no reason why not..

[Brettw500]

Definitely! No question about it...None at all. Physics isn't real, it's just made up to scare people. Like the Boogie-man!

[AGuyWithDownsyndrome]

fake...

[jazkat1]

how so?

[nathanmarkbooth69]

its basically the magnetic brake effect like putting a load on a generator the revs drop down.

[tatakaetarantera]

i know magnets get weaker after every drop but this magnet seems too weak to be rare earth.

[TomPuzzle]

Basically what happens is as the magnet falls over, it creates a current in the copper (induction). This current in turn generates a magnetic field, which is opposite to that of the magnet. As these magnetic fields repel each other, the falling magnet slows down. If the magnet slows down, the current drops and the magnetic field is lost. That is why it in the end does fall over instead of repelling itself.

That is, if I understood my physics lessons of last term well.

[fatmanprime]

I concur.

[FireBirdsGo]

Thats amazing! But does anyone have any idea about why this happens?

[jazkat1]

my guess is that the end that was on the copper is still trying to stay on the copper when pushed over but the strength of the force that is making it fall is more powerfull so it still falls, just slowly. that's my guess anyway ^_^

[psycopyro001]

watch?v=iABmUEH5s0k that video explains it.

[TeamGreen3342]

ill take that copper off your hands if you dont want it...lol

[Pzski99]

I bet that if he placed the magnet on the floor, on end, that it would fall over when pushed.

[icebloomafoo]

Of course it would. What he's showing in this video is the "magnetic braking" You'll notice the magnet falls very slowly for it's size/weight.
