Neodymium Magnets Magnetic Ball Spins for over five minutes LOW FRICTION BEARING

[PaterFrog]

I'm missing a screamer pic. :D

[thecoolest888]

get 216 and that would be fun!

[012Jac]

must read this. once u have started there is no turning back. a litle 10 year old girl was raped and murdered in 1945. her body was not fund until 1947. then a boy last week read this and did not copy and paste this message. the dead girl appeared in his room haunting him and killed him. if you do not copy and paste this onto 10 videos 30 minutes the dead girl will appear in your room tonight and hant you and kil you. well you better start to copy and paste to be saved

[MucusFelidae]

My balls spin less.

[bitchassgecko]

is it only able to stick on that one point and spin the way it is right now or could it roll the other way?

[tommymorey]

Or real music like this. Thank you.

[tommymorey]

God, how my heart searches for rea

[keat43]

Thumbs up if you're tired of people saying "Thumbs up" after they say something, as if they're trying to take a survey.

[JacobSijsma]

@keat43 Well even though your own comment apply's to that, it is still funny xD

thumbs up if you skipped to the end

[nugget141000]

mega bucky balls !

[SunTrapped]

Good idea of not trying to play with them, working my own project got my figures pinched between two and one side had hot glue on it so you can understand, Ouchhh!

[lexichronicle2]

If you search for 'air bearings' some of those can spin for minutes just with a flick. They're used in tool shops for sharpening end mills, in spindles for precise high speed motors and for optical benches

[PanORotta]

i want my balls magnetic

[skunkape49]

are they stronge enuff to make the hair on you arm stand up and do they give off electric shocks like the novelty magnets im look for did back in the 1970s

[SchMasHed]

Thumbs up for who watched the whole thing ...

[scriptedBug]

fake!

[spaz130789]

i will argue that the magnetism is not the only variable at play here. Sure, the friction between the 2 LB ball at the bottom, and the one directly above it is very low due to low magnetism, but if you look closely, the friction is also low because all five of the smaller balls are spinning as well, causing their kenetic energy to feed off eachother, and allowing much more 'spin' time. however, if you were to hold the ball directly above the 2 LBs ball, the spin time would be much lower.

lol if ur ot 480p on this u can see his whole entire front yard!

[cyanideisabitterpill]

holy shit Batman!

[jigley9higley]

This is an interesting video. You should consider putting a mark on the spinning ball so that it's more obvious when it's spinning and when it's not. Still, I really liked it. Thanks for showing us this.

[RamsesReturns]

For every small ball you places above your last ball, it would have spun even longer, or did you say that it would not hold any more?

[vitpino95]

Nice, but...how do they work?

[MinGophers]

What's the name of the piano music

[peteacher52]

It might spin longer in a partial vacuum as it was probably friction against the air that caused most of the slowing down.

Btw, a flat one of these neo magnets put on the oil filter of your vehicle will attract and hold any suspended metal particles in the oil. For reasons I don't understand, even non-ferrous particles are held as well.

[flexairz]

@peteacher52 Non-ferrous particles will not be attracted by a magnetic field. These parts we probably stuck between ferrous particles or contain trace ferrous material.

[eazolan]

The reason it's spinning so long, is because there's almost no friction stopping the ball. There's the air, and there's the one point of contact on top.

This negates the whole purpose of a ball BEARING. It's in the name. It needs to bear a weight. Which means at least 2 surfaces touching the ball, and if you're actually using this as a bearing, you'll need a groove or a guide or something to keep it in place.

If you want to improve ball bearings, you'll have to make them not touch.

[peteacher52]

@eazolan In 1959, my father, a dentist, bought his first "Air-rotor" high speed drill with mechanical bearings lubed by a fine spray of non-toxic oil in the compressed air. It turned at 300,000rpm with a characteristic high pitched squeal. Regular servicing needed. By the 1980's technology had changed. The rotor now floated on air bearings and speeds of up to 1million rpm were possible, between 500 to 750,000 being more usual, with only a muted buzz and hiss to be heard. Very reliable.

[ElnaCopper]

terrific!!!!thanks : ) :) : ) happy 2011

[thelegendbullet937]

I can't wait till they make fans with these bearings!!! It'll be awesomesauce :]

[otherpower]

I'd have to argue that the magnetic field has little to do with it... simply that two very hard balls (in this case the Nickel plating on the balls) have a very small point of contact and the friction is very small. It's neat though - we've made mobiles this way that dance in the air for many years....

The same thing could be achieved though without magnets, just hard steel balls if you could make it stable enough (perhaps a gyroscope) and gravity. I would not call this a 'magnetic bearing'

[callmeshane303]

It's witchcraft and sorcery.....

In the name of Jesus begin the inquisition.

All unbelievers must be killed in the name of our lord to show how much he loves us.

[RunAMuckGirl2]

@callmeshane303 LMAO!

[JENNYRED4EVER]

@callmeshane303 WTF are u talking about?

[zacandmillie]

Hello Dan, Always enjoy your videos. Now I guess these magnets can't be bought and posted in the mail. Imagine the concern when the postal workers have to deal with them in a package. Just how are they delivered and are they for sale to the general public?

[1BustedMyth]

Search "KERS" flywheels with magnetic bearings work well, there was a Bus in the 1970's that was electric and stored its power in a flywheel.

Flywheel can be used in any application in place of or with a battery, excellent for regenerative braking in Electric Vehicles.

[bodryn]

@1BustedMyth Flywheels would be a great alternative to batteries in northern climates where batteries don't do well in subzero weather.

[1BustedMyth]

@bodryn, That is a really good point!, I'm in a hot climate, so don't think about that much. Great idea buddy

[noelsingletary]

Imagine how long it would spin if you could accelerate it to 10K rpm.

[JimboJitsu]

nice demonstration, is this similar to the electric floating trains I had heard about in the 80's?

[wyattlisadana]

Holy Shit!! I love how your balls just dangle!!

[wyattlisadana]

Holy Shit!!

[UniqueV170]

Somebody send this to mormons.

[slchilds100]

This might be what I am looking for for my experimental vehicle.

[slchilds100]

This might be what I am loking for for my experimental vehicle.

[R4WC0D3R]

Cool

[patsaint]

you sell this product?

[f38stingray]

You could also try spinning it up with compressed air - you'll lose a lot of friction if you reduced the wobble at the beginning.

[mipoleon]

Now it would really be something if Dan could harness more energy from than than it takes to get it spinning.

[9thincarnation]

Heavy duty magnetic bearings were invented some time ago. This I don't believe fits the definition of a bearing as it is not doing work or transfering energy.

[kmg501]

I would be interesting to now coat the ball with one of those poly coats you put on a car once a year. And see how long it spins then. IE if you get any significant surface disturbance reduction.

[FAIZCOOL2008]

NOW MY 8:02 MINS ARE WASTED :)

[iamafractal]

could you do this again with some lines drawn on all the balls so we could see more clearly how well they all spin?

[earthmoonmars]

OIL hmmm, how abaut slick 50? it would or should, extend the spin time for longer, /it should because it's the sliperyest substance known to man/

[vox1philippines]

i love it !

[nephozo]

magnets are a somewhat suppressed source of utility / energy

that the very use of them would change the world as we know

i think that is why you sometimes see so angry posts regarding them

cause change scares people

want to see more magnet videos.THANKS :)

[youkeylaylee]

christmas ornament at 1:04

[w3bguru]

very cool

[Theskidmark61]

Interesting...I will work that into one of my projects!

Thanks and Keep up the good work!

[klaymen]

Would have preferred to see this spun with some sort of device measuring the starting rpm's. This is pretty much useless for comparing to anything.

[Shaunt1]

Is there a way to arrange magnets so that they move for hours or more that can be used to generate electricity?

[hellstradingpost]

@Shaunt1 no, You can only get a portion of the energy out that you put into any system.

[tectalabyss]

Very Interesting. would be a great way to reduce the drag on many thing's we use every day Thanks for sharing.Tec

[Virasana]

I can see how using opposing magnets to lift something away from the bearing surface is usefull as in VAWT levitation technology.

Do you see this 'hanging' type of friction reduction being used somewhere? If so where?

[methotfoufou]

wow that's pretty cool! what kinda home application are possible with these kind of magnet??

[Timpy2000]

sounds like music from the sims, when ur in build mode

[ihatetechtalker24]

@Timpy2000 dood i thought the exact same thing XD

[SydbarF]

As always this is cool stuff....maybe when I move to Port Saint Joe next year Ill run into ya somewhere....Mexico beach is just the bomb..Cape San Blas is beautiful...

[SpanishThug]

What would happen if you manage to get it to a higher speed?

[GreedIsYourGod]

Your magnets are starting to chip. Unfortunately that means it won't be long before they completely disintegrate. You can save them by cleaning them really well (not with water) I use adhesive tape to pull off all the stray bits and chips. When really clean dip them in a strong (slightly elastic) type of epoxy and allow them to cure. You can use sandpaper to round off the uneven blobs later. I have a big powerful pair of rare-earth magnets I treated that way that have lasted about ten years

[rainbowsalads]

Was that Denise singing rather well indeed in the background then? : P

[MrROTD]

How long would it spin with dimples?

[deadman12078]

Sexy

[Intransitman]

Reminds me of roller bearings! lol

[Janus5711]

More vids with piano music!

[kdknitro]

they have magnetic bearing already man, i used to do with when i was 8

[yellowmetalcyborg]

@kdknitro Me too. I used to do this when I was 7 when my parents got me a Magnetix™ set.

[vener6]

Who's playing piano and the name of the piece please ? :)

[AssilalOmega]

dude actually ...u can increase the magnetic force with electricity ....or an electron beam....didnt u do that? but if u do that with the the products will be a slithly radioactive metal (depends on what metal ure using)...

[AManOfHope]

Great! Next thing you know he is going to figure how to make gravity defying, blood thirsty, metal balls. If you see Dan wearing a quaker hat then run like hell!!!

[GREENPOWERSCIENCE]

@AManOfHope [[:-∑

[beefptty]

@AManOfHope lololollolol



[locouk]

You could spin it up using a low DC current, basically a homo-polar motor. For the guys who say to oil it, the oil would add to the friction and make it slow much more quickly due to the oil's viscosity.

[mahirharoon]

@locouk what about trying something with no viscosity

(i.e- superfluids) like rubbing liquid helium on it (but unfortunately , due to their low viscosity , the helium will not stay)

[locouk]

@mahirharoon I think you've answered your own question, I guess a thin coat of graphite or teflon might work though.

[spraggerdog]

Would have been nice to have put a sharpie mark on the last two ball, yes the question of oil is a good one ?

[IceFritzLanger]

If you like neodymium magnets, have a look at GilbondFac, a french university guy, he is great with those =)

[aCagedApe]

Cool video..

[sunkazz]

omg! i'm crying for my past 8 minutes XD

[jab0805]

I'm curious to see if the addition of a lubricant will increase the spin time.

[v3dDotRu]

add oil

[joshcryer]

This reminds me of Magnomatics's PDD gear (search for it on YouTube).

[muddymuddymuddmann]

THOSE ARE SOME BIG STEEL BALLS YOU HAVE THERE DAN. MAKES ME WONDER WHERE THEY CAME FROM. THE LOW FRICTION BEARING APPLICATION IS BETTER THAN I THOUGHT IT WOULD BE. SPINNING ON VERTICAL AXIS IT SPINS WITHOUT LENS LOSSES OR EDDY CURRENTS.

NEVER THOUGHT OF THAT!

MUDDy

[madjimms]

Those magnets are holding yer steel balls. Are you related to Chuck Norris?

[Robert697]

Unfortunately as soon as u put a load on it, it stops. However, I recall some research back in the early/mid-90's looking to using huge/heavy flywheels to power cars. A small electric motor would spin the wheel up overnight, and the car would theoretically draw on that stored energy. Going down hill or breaking would also add energy to the flywheel. Problem was calibrating the flywheel so that it wouldn't fly apart. I wonder if the technology exists today to create such a flywheel.

[Arnthorg]

You should really re do this sometime with the ball painted half white, a drop of oil and using compressed air to spin the ball. :D

[4jamesh]

where did you get the magnets from?

[58belvedere]

how long will it spin with a drop of oil on it?

[valhar2000]

@58belvedere: This has more to do with the fact that there is very little surface contact between the balls than anything else. I don't think oil would help very much, given how small the surfaces in question are.

[iwant2cryTUBE]

@58belvedere I'm wondering the same thing myself. I suspect it wouldnt help much in the long run because both surfaces are already smooth and contact is minimal already. Adding oil or grease would attract debris eventually which would probably result in a net slowing of the rotations, even if the ball initially spins longer at first.

[veganath]

@iwant2cryTUBE IT TAKES BALLS OF STEEL TO RELINQUISH OUR DEPENDENCE ON OIL :-)

[peteacher52]

@58belvedere I was wondering the very same thing! Some spray lube like Amsoil MP or Innox.

[derman077]

I went to the bathroom and came back at 6:45. Thanks for the extention , lol Really cool science demonstration too!

[8razar8]

add a little wd-40 or teflon.

[TasteMyVideos]

Yeah, there is no need to say Merry Christmas or Happy Holidays at least...

[GatheringSticks]

very Mc Escher esque @ 1:53..awesome vid.

[taofledermaus]

It's surprising how much energy a large ball bearing stores when you spin it. You probably could have put just the 2" ball in a glass or ceramic bowl and got it to spin as long or longer. The magnets make it cooler though! I got a small 1.375" (7oz) ball to spin for over 2 minutes, just spinning it with my hand like in this video. The heavier the ball, the longer the spin. They spin much longer than anyone would guess.

[depravedpuma]

What would be the practical aplication for this set up??

[KnuxVeeone]

@depravedpuma Would like to know the answer to this myself although as a demonstration of low friction energy transfer the video does it's job. I think the idea is, if we can harness that energy it would be a very effective energy source.... Just need to find some-way of connecting it up....

[MRIWANTTRUTHPATRIOT]

@KnuxVeeone they already have made an engine out of magnets in australia the ma n was shot yt it

[lexthegoose]

wow so glad i skipt to the end!!



[budchin1]

Put a rubber tipped end of a drill bit (kind of like a spinning top) in a dremmel and you can spin the ball without using your hand, and it will go for a loooooong time.

[davidlightsnack]

It would spin even longer if you made the two contacting surfaces more smooth, and if they were in a reduced pressure enviornment, or even better yet, a vacuum.

[yellowmetalcyborg]

@davidlightsnack A vacuum wouldn't do a thing, there are no resistive surfaces to dissipate energy.

[davidlightsnack]

@yellowmetalcyborg , but the air around the spinning ball produces friction. So if there is a vacuum, then there is no surrounding air to create friction. I think it would make a difference.

[yellowmetalcyborg]

@davidlightsnack It does produce friction, very little. Most of the energy is dissipated through the pieces of metal though. The amount of energy required to pump a vacuum would be far superior than the amount of energy a vacuum environment would save. Besides, a vacuum doesn't last forever, so you would need to pump another vacuum sooner or later.

[onmhyway]

Keith Jarret is my guess.

[theafrodude22]

cool video

[theafrodude22]

there goes 8:02 mins that i fast forwarded to less than that i will ...

[1BustedMyth]

Best Bearing known: Solar System

Earth: 40,070 Km wide, 5972000000000000000000 M Tons (5.972 Sextillion)

Rotational speed: 1670Kph at the equator

Orbit speed: 107,000 Kph, travels 942,000,000 Km per year around the Sun

One full orbit: 365 Days 5 Hours

Distance from the Sun 149,000,000 Km

[HARMANHOUSE1]

HEY YOU SHOULD SPEED IT UP WITH A DRILL THEN SPRINKLE SOME GRAPHITE LUBE OR A DROP OF FINE OIL TO SE IF IT INPROVES THE SPIN TIME. SORRY FOR THE ALL CAPS JUST NOTICED LOL...

[Gmc42082]

that would make and awesome disco ball, just glue some mirrors around the ball bering

[noferblatz]

Now as an experiment, what would happen if you added a dot or two of oil to the top of the bottom ball bearing? How much would it lengthen the rotation time?

[mccunecp]

those be nice to build a wind turbine generator lol

[psynthpriest]

@mccunecp Some companies have actually used neodymium magnets for that, but they don't really warrant the cost involved. I could try elaborate but it would be way too long to post on youtube. Even so, I think there is a potential place for them in power generation if used correctly, just not in wind.

[Sodorii]

Would be cool put it in vacume and see how much friction air gives

[robertof84]

that was freaking long spin...

[GamepitDAngelo]

To all the people complaining, he warned you.

My question is how can we use this energy for something useful? Or how is it being used?

[2Bibleppl]

@GamepitDAngelo

Good question.

[DreamPharaoh]

At 5:42 I started to notice it finally slowing down thanks to the sunlight, I was wondering how you were going to show us it was still spinning at the beginning lol. Because the magnetism was holding the ball it seems that the friction was reduced quite a bit also reducing wear and tear. I wonder how long it would spin with a lubricant. I believe they are using this for the newer wind generators now, I assume they are using graphene as a monopole to eliminate magnetic resistance. Thank you

[ohsk8an]

Where did you get the ball bearing?

[dzgfdg]

ooooo you touched my talala

[CreamPie9uy]

I wonder if you could use a bearing like this for a vertical axis wind turbine to reduce the friction and make it more efficient. Out comes the pen and paper...

[operator223]

and the point of this is ?????????

[pabyizzy]

@operator223 He actually says in the description that he doesn't know of any practical use, it's just amazing how it spun for over 5 minutes from a hand spin :)

[wwlegomaster]

2nd

[mobius1ace5]

oh wow there goes 5:37 of my life :D ... but seriously, cool stuff! Great video!
