Frictionless (Almost) Permanant Magnetic Bearing

[kayaking4autism]

I tried to make one myself (see above) but I didn't have a spherical magnet and I've also noticed that if the magnets aren't perfectly spaced, the magnets act as dampers rather than bearings. I've also only used 12 magnetic sections which aren't as good as kunjione's 16. I'm using square magnets instead of round ones which aren't as good either. I take my hat off to you sir, your one must have cost you about 300 quid in neodymium!

[interplexer]

Nahh, you're all wrong, It needs a Hemi V8 ! ! !

[eilselyiu8]

if you calculate it more to make it a perfect round shape, and make the nail as thin as needle, it will last much longer.

[SnowboardTrucker]

It runs much longer without magnets !!

[MucusFelidae]

You have much spare time. I have too, but am much too lazy to build useless things.

Why do people insist on putting there "music " of choice on a vid,I admire what you do but for fuck sake keep your tecno euro crap off the vid

[ripleyrichard]

cool as fuck

[deepcut66]

What a thing of beauty, really gorgeous mate.

[DanVonfire]

hi, what do you do for a living, are you for hire as an egineer

[theyellowk123]

Put it in a vacume...

[lleksikon]

@theyellowk123 Perfect vacuums are impossible to create (at least as of today).

[theyellowk123]

@lleksikon but it would help make it go longer

[lleksikon]

@theyellowk123 You are absolutely correct :)

[KingSlimjeezy]

impressive. you must have quite the workshop. very clean

[peskeybobcat]

Man that thing has been loved..

[TheRealDealinlife]

You did a good job. keep up the good work!

[ncranfill]

what you have done is almost exactly what i have imagined except that it appears as though you have done nothing to turn it into a self sustaining generator.

[Magnetmad]

Nice!

if u can find away to collect and return it would run for quite awhile on its own

[leoxy64]

This reminds me of an old mechanical computer

[oysterlicker]

Wonderful. Imagine using this in a brushless motor...the RPMs gotta be crazzzyyy!

[Me102288]

@oysterlicker the ball bearing at the end woulld heat up fast enough to eventually "weld" itselt to the rod.. another magnetic bearing and you could :-) :-)

[Uneakdawg]

Hey crazy fuc off! u do better, then show us something!

[1crazyfocker]

get idea but the gapping in the large cylinder and small one created sticking points, so thats why it stopped faster then if you would have just used bearings, the magnets slowed it down, I am not say magnetic bears dont work, i am pointing out a flaw with your system. by spacing them so far apart it slows it down rather fast. but great work keep it up

[Me102288]

the ball bearing = friction, capture both ends in magnet bearing and give it a spin, then put it in a vacuum chamber, then you have perpetual motion?

[tonfazg]

@Me102288

Spinning magnets cause induction of electric current in all metal parts that are in range of changing magnetic field.

That current has its own magnetic field which has effect on primary magnetic field in a manner that is trying to prevent change of magnetic field that caused the current that created it...i dont know if that makes any sense :) anyway you cant make it spin indefinite, because there is always that force that works against change...spin.

[Me102288]

@tonfazg in metal I know, but magnets spinning in between each other does not. And if they're set up so they're fully captured they tend to spin naturally with the magnetic field from the magnets themselves, not saying lining up 36 magnets on an axle/cup isn't hard.., (cough) callways v-gate lol.. its not of that princible though, if you squeeze a magnetic field hard enough with another they tend to do all kinds of need stuff :-\

[LabyrinthSounds]

@tonfazg lenz's law :)

[Helicopterpilot16]

Put it in a vaccum chamber it will be permanent!

[carbonandchemicals]

@Helicopterpilot16 No, even then it won't be permanent due to loss of energy through thermodynamics. However putting it in a vacuum will definitely increase it's efficiency.

[bboybenja87]

WHERE DO YOU BUY ALL YOUR PARTS FROM?

[shawnki91]

EXCEPTIONAL WORK! Damn well done. This is a really nice application. Have you patented this idea?

[todicky]

How much did that cost you to build?

[bangzilla]

this song is gay

[brandond707]

pretty good...

[andytysn]

very nice work

[Footrek]

what is that large steel disk, just metal or a large magnet?

very good craftsmanship, work of art.

[kunjione]

@Footrek The disk is just a housing to hold disk magnet which are made from aluminium.

[isidoropotente]

Bel lavoro, complimenti

[zevokes]

WICKED!
