floating pencil - diamagnetic levitation

[cabadra]

I'm pitching a pretty cool diamagnetic levitation sculpture on kickstarter. (Search for 'levitation'.) Fully adjustable, so you could buy your own magnets and experiment too!

Actually, more correctly, floating pencil *lead* but close enough! Don't want to put too fine a point on it! (ar ar) Thanks for posting.

1:09 U BROKE IT LOL

[burritomaker69]

so this is just store bought graphite and powerful magnets? Also do you have to arrange the magnets in the formation you have here?

[stevesrd]

Ever tried running some high voltage through clays, rocks and the like to see if something levitates, just a suggestion for those looking.

[fuelban]

if you get a glass tube, put two magnets opposing in to tube, say glass tube = 100gr & each magnet = 100 Gr, total weight is 300 Gr, NOW with the assembly on scales to show weight, the top magnet oppossing, though floating susspended, it still registers it 100Gr waight in the total shown on scales, which is 300Gr, levitation would not register weight of levitated object. on sclaes at all.

[fuelban]

intresting stuff, but my question is.... is it {levitation} or {suspenssion} they are two differing things,

weight of magnets, then weight of item {lead pencil} add these weights, and do it on a set of scales, if weight is shown of magnets only and not pencil weight, its levitation, but i think its susspenssion,

thom.

[matthias2986]

so you are saying the object in suspenssion would not press down on the magnets increasing weight on scale? rather it would be without weight?

[fuelban]

Yes youre correct.....Items that are truly levitating would weigh nothing, weight shown on scales is in fact the amount of gravitational pull on the item, no gravitational pull = anti gravity = levitation, which = no weight registering on the scales, I know its hard to get the old head round, LOL, my old head was hurting too !!! LOL, think I will put a video up soon to let you see what I mean.. thanks for comment.

[stuuk1958]

if it would not be without weight, the magnets would be creating the weatless illusion, wright?

[85kanuto]

That´s really amazing !

Are that N52 neodym magnets?

[sanin92]

my physics teacher doesn't believe in diamagnetism, what a dumb shit

[megaverse]

indeed, what does he believe in ?? that's wierd though ?

[sanin92]

he just does not believe in diamagnetism because he has never heard about it. my teacher thinks he knows everything

[megaverse]

a teacher in physics ...hmm it would be about time he learned about this, frankly, make it a mission lol !

[sanin92]

lol, I bought some pyrolytic carbon and neodymium magnets so i can show him

[megaverse]

Now why didn't i think of that lol ...great it will be the ultimate proof...you'll be able to say "in your face"

[sanin92]

hahaha, i will say that , he is going to hate me, ill tell you when i show him

[sanin92]

he saw it like 2 days ago now, this shit was so funny, he was playing with the levitating graphite like a child, he was speechless

[boxofcrap1]

i doesnt work

[chatterBln]

Of course it does work. :-)

Just try it as discribed below.

But pay attention that the carbon lead isn't too thick and so too heavy to levitate on its own.

The diameter of this carbon lead is about 0,7mm or 0.027inches.

[awesomeideas]

@boxofcrap1 Some graphite in mechanical pencils is weakly paramagnetic, as certain companies add iron to the mixture.

[highvoltagefeathers]

@boxofcrap1 It does, keep at it,



[bestSVMS]

do you have to do this with like 10 nydimieum magnents?

pr will 1 work

and is that 0.9 lead, because its thiker

[chatterBln]

The diameter of this carbon lead is about 0,7mm or 0.027inches.

The number of magnets depends on the length of your lead.

[pimgta]

is it electromagnetic or just sonme normal magnets? I want to make it too!!!

[chatterBln]

These are just normal strong neodymium-magnets and a graphite-lead from my pencil.

Try it an enjoy. :-)

[sanin92]

is pencil graphite-lead as diamagnetic as pyrolytic graphite?

[mysteriose7en]

no, because of the clays mixed in with the graphite

[sanin92]

and do you know if graphite-lead is more diamagnetic then bismuth, and i think pyrolytic graphite is more diamagnetic than graphite-lead, but tell me what you think

[CosmicWabbit42]

regular pencil lead is just about as good, considering its a thousand times cheaper.

[mysteriose7en]

it is actually far worse, due to clays being mixed in

[mysteriose7en]

its actually far, far worse than bismuth, due to clays being mixed in with the graphite. pyrolytic graphite is better than bismuth in dimagnetic terms, but only in one direction

[sanin92]

thank you, something weird happened with ur comment though, did u want to post half of it then post the rest of it?

[mysteriose7en]

yea

[CosmicWabbit42]

with my N50 array here, I get good levitation from regular pencil graphite, considering the price difference, for playing around on the desktop pencil graphite is just fine.

[321815730]

wat caused the lead to move back and forth

[bestSVMS]

he pushed it

[Darkbain]

Koo vid. I have my stash of magnets ready :).

[ymi2b]

Stoer! Cool.

[jasonguyperson]

it's the graphite.... sick! that is awesome!
