Strongest Magnet in the World in 1963

[xLoliChiDesuu]

this magnet will last fro years and years.

@03SilverMustangGT Ikr

[03SilverMustangGT]

They did all that work for scotch? LOL

[MaverickMachine]

Sir, why are you at this top secret facility?

I was lost, so I followed my compass North!

[ongxizhe]

@MaverickMachine Magnets point south, though you can still reach north by following the opposite direction which the magnets point..

[TheBandScanner]

I would have liked to hear an honorable mention about the works of Joseph Henry; he also came from that area of New York.

[EdisonExploratorium]

@TheBandScanner we have a page on him, probably will do a video about part of his work later this year

[fulely]

Nicola Tesla mentioned many times but gets no credit, boooooooooo, but nice work GE

[VisionClarity]

@fulely Don't you mean Bell?

[shadowsjc]

Suddenly, Magneto

[mattybock]

back when scientists gambled with the earth itself for whiskey.

Nikola would be proud.

[TheRedNation95]

the sucess of the large tesla coil.........

[MrSoulTracker9]

i feel bad for thinking of this, but i bet the most effective form of torture would be to use a magnet strong enough to pull the iron around in your blood, imagine the pain, just need to get a small enough size magnet to run it down your arm

[seeheers]

1:30 all for the love of beer

[realvanman1]

Cases of scotch for a prize; What a cool era...

[doceigen]

A 10 T magnet is used in a small NMR device nowadays.

[veritas0071]

200000 times stronger than the earth's magnetic field at the surface. That's a meaningless statement.

[ganaschico]

@veritas0071 how is it meaningless?

[MattsMisc]

i built at a homemade gamma radiation shield. it's comprised solely of alcohol. har har

[SoulEater8754]

@Nexayus YE lol

[artofnick]

so we're up to about 34 tesla now?

[SuperVeshi]

Amazing all for crates of scotch lol

[zawzero]

I ordered a pack of 16 of these for about 5 bucks on ebay.

[patrikk777]

The guy in the beginning looks like Owen Wilson

[SlaginnMetal247]

i mean if scientists have been doing deep research on magnetics since 1963 couldn't they make a vehicle that can fly really fast and all most out of space just by the earths magnetic poles

[SlaginnMetal247]

ufos fly by the magnetic poles idk what the big secret is

[RifleKingxx]

do magnet help u get a pop tart ?

[MMIIXX]

@RifleKingxx only if she is wearing an underwire bra.

[AmericarefulHD]

Press 6 for 6 :D

[chickenpoper]

@martyn347 thats at the surface, at the edge of earths magnetic field it is much stronger

[Tenatiouz]

@darkeyce02 lololol I love that blender man!!!

[Deviantblade88]

@michel6 LOL! What does being American have to do with any of this? Books are also written by other people. Just like the internet. Unless it's a record, or transcript of an actual record it can all just be opinion. On the internet we read opinions on a screen. In books we read it on paper.

[michel6]

@Deviantblade88 13yo kids rarely write science books, anyway they come to internet to post "articles" here and there. Worst of all, anonymously. Therefore I disagree about the supposedly equivalence between internet and "real paper". And about your Americanism question, it's unnecessary to write here about the historical competitiveness between USA and any other country with exception of Israel, which forms most part of the Nobel prize mafia. They even rename bacteria to their taste (eponyms)...

[Deviantblade88]

@michel6 Disagree away. Nobel prize mafia. LOL Man people are always crying about America. Whining about America on youtube isn't changing things.

[andrei128]

@EdisonExploratorium Some say Testa had 3 balls ... others say he invented Internet ... some say he was an alien from Mars ... just stop with pseudo-science please !

[lebensraummetal]

@andrei128 All we know is... he's called the stig!

[christos1709]

you guys got paid in scotch...EPIC

[celebration81]

@EdisonExploratorium Ganz company was the first firm which introduced the AC in industrial scale (since 1878) You forget to mention the other great introducion of ganz: The so-called "parallel connected" e.distr. system and transformer. Bláthy was the great Ányos Jedlik's disciple. You forget to mention of the introduction of parallel connection by the ganz company in the tranformer article of your webpage. Greetings from Hungary.

[mr1000rx]

Give on of these to James Roney and make a shield for it and hey presto. One VERY strong motor!

[TheBlacksabbathfan9]

@gareler movie night with John Paula?

[TheBlacksabbathfan9]

@gareler movie night with John Paula?

[CockroachGiraffe]

The end song is from zelda

[gareler]

were have i heard the song at 2:18 before?

[peepeevagi]

Now we have a super magnet so super... magnetic that it makes any water-based object float. Like frogs (Which are comprised mostly of water).

No purpose other than research and shits n giggles.

[Stannik1234]

Press 3 often..an youll hear a frog:D

[gui123dias]

effin magnets... how do they work?

[airpartical]

What is the song starting at 2:33? Thanx

[audveltadmuna]

@martyn347 obviously

[77robinhood77]

@martyn347 on surface, remember.

otherwise, every magnet on the surface could be able to deflect radiation from de sun

[BadRick951]

build a magnetic motor look it up

[lolbrb100]

Damn it I was just getting into it...

[thelazyest]

@boxa888 ivv see wat you wer talking about on history channel it was tight

[Vhozard]

Retarded comments below me

[lordtarnerran]

But will they blend?

[lordtarnerran]

But will it blend?

[RadicalMassacre]

hmm, i dunno, is it a good idea to go messing around with magnets stronger than the earths magnetic field? could you mess it up?

[Jpieka19]

@RadicalMassacre lol Exactly and where worried about 2012. we just make our own magnets.

[AlphaMaleRyan]

i believe this is an superconductive electromagnet

[hunterziegelmann]

Not more powerful then earths magnetic feild only more powerful then earth's magnetic field AT THE SURFACE

[4NG3LxD3M0N]

if its so powerfull then something in the world would of broke or something

[debrainwasher]

@martyn347, I would rather laugh at yourself instead of earth's magnetic field (created by a dynamo-effect). According to the dipole equation, magnetic flux density decays with 1/r³ (third power of distance) Do the math yourself how strong an equivalent magnet must be, when you assume earth's radius with r=6'300km.

(\_/)

^_~

[daenumen]

@debrainwasher in terms of relative distances, a 10T magnet that is spherical (for mathematical simpliticity) will have a larger flux at 2r from its centre, than the earth at 2R from its centre.

[debrainwasher]

@daenumen If you wanted to answer the question, with that I've challenged martyn347 in a simplified manner, I'd rather suggest, you used a homogenous cylindrical rod magnet, the dipole equation and the well known relation |B polar|=2|B equatorial|. Then, there is the relation (written in differential form) B=dPhi/dA; with B=Flux-Density [T], Phi=Flux [Wb], A=Area [m²]. Remember, B is a vector.

(\_/)

^_~

[daenumen]

@debrainwasher wrt to the differential rep of B, that a bar magnet will have a greater value of B, inherently, and hence its flux is larger per perpendicular surface area permeated.

also, taking the dipole magnetic model of far field strength for simplicity on the dipole axis, that m is greater for a 10T magnet than for the earth.

|B axial| =2 |B equitorial| - from the dipole eq, a theoretical model for a 'point magnet'. so does not apply to the earth, except at very large distances.

[debrainwasher]

@daenumen "...so does not apply to the earth, except at very large distances."

Correct. Is r=6370km large enough for you to consider far-field when L and D are variables ? You have got the point, how to crack this infamously differential equation system to 'replace' earth's magnetic field by a smaller bar magnet (in first approximation, of course). Additional hint: Use Gauss's least square error method to minimize the polar- and equatorial errors (calculate vectors by components)

(\_/)

^_~

[daenumen]

@debrainwasher im not sure you are following...

a bar magnet of the strength of the earths field ~ 30 mT, is much weaker than the magnet in the video...

if you want to consider a distance of 6300km that is only twice the size of the earths outer cores outer radius.

a typical spherical neodymium magnet will have a larger mag field, and flux, at several times its radius.

this is what i was explaining to you in my last post?

the hint is redundant, & what are you defining L and D as?

[daenumen]

@debrainwasher since B is the 'magnetic field strength', and as expressed in differential form represents the flux PER unit area, it is universally comparable.

if you wish to use the dipole method, you would have to approximate the earth as a POINT MAGNET, such that at 6300km, it has a value of ~30mT, hence, at zero distance from the surface of the magnet, the field would be HUGE.

however, a bar magnet would still be GREATER.

[daenumen]

@debrainwasher (cont) given the same approximation to a point dipole.

this will give a crude approximation, hence why the usual differential result is prefered, as it negates the necessity of this sort of approximation.

looking at it another way;

if you wanted to make a magnet that was as strong,as the earths is at a distance of 6,300km, given that M of the earth is relatively low, a neodymium magnet would be smaller than the earths core, and still produce the same field at 6300km M=nm

[CommentClown]

What is a Watt of energy?

[debrainwasher]

@CommentClown, possibly somthing like 'the weight of time' [kg].

(\_/)

+_+

[hr1100]

@CommentClown The product of current and voltage.

[ExpertOfSound]

This magnet could probably kill you by pulling the iron out of your blood through your skin...

[13stAndreas]

lol i have exactly the same Bausch & Lomb stereomicroscope seen at 1:14, nice :P

[CrazyMan2140]

200.000 thousand stronger that aleliuja:D

[XenTheKiller]

So you have been in the core of the earth ? There is no magnet that has a magnetic field as big as earths

[skittlepower95]

@martyn347 wtf no ur stupid

[reznu]

... if he was wrong then wouldn't every piece of metal be stuck to the ground? yeah .. think about that one STUPID.

[XenTheKiller]

because the bar magnet is more densitive (that may be wrong spelled) and the earth is not 1cm wide....

What will you come with ? Like everyone else and start insulting like a....... Or accept it and leave or pass back a good truthful argument....

I never said that my comments are "Truth" or "Facts"..... What i wrote below may be wrong by intention or may not. You decide if you wanna be a ********* or at least show some intelligence <- I never said that you didnt have so dont come with that

[Babis995]

wrong

[martyn347]

@baconator490 becouse their magnetic field is too short,i saw that on national geographic

[XenTheKiller]

@martyn347 Then why cant EVERY magnet in world move planets if they are SO MUCH stronger

[martyn347]

@XenTheKiller it s a little hard to explain try google it

[reznu]

... your stupid. are the tiny magnets as big as earth? NO if they were could they move planets? of course,STUPID

[XenTheKiller]

Whoa... And you call me stupid.... You should call me Smartass because i was being one!

Magnets from earth cant be stronger than the earths magnetic field because the magnets come from the earth... And unless you havent been to the core then i suggest (to every scientist) to shut the f* up because magnets are UNPREDICTABLE

The earths field is measured to be 5*(10)^-5 Tesla, a bar magnet is measured to 10^(-2) Tesla.....................

[67tr876]

@reznu dumbass

[Srlancelot39]

@martyn347 no.

[nukeum2]

Could this magnet some how be utilized in space to protect astronauts from radiation?

[iHackForum]

@nukeum2

Possibly, I think there is a few projects setup to test it.

[AlphaMaleRyan]

@nukeum2 why is every one so uptight about radiation?

[CampKohler]

@nukeum2 No, when energized it would quickly suck the astronauts down to earth and stick them to the USS Mississippi with such a smack they would be so dizzy that they courldn't really enjoy a Hawaiian vacation.

[Assi2004]

@nukeum2 no.

[Blazerelf]

@nukeum2 from alpha and beta radiation yes, but not from gamma it sadly wouldn't do any change at all

[Ramiromasters]

That is prob one of the most ignorant statements I have ever heard. I'll save it and let my future generations read it so they will see how far behind in evolution humans where in general at this time.

[tisnyne777]

Haha,, u idiot did seriously think I was serious? your the ignorant one stupid....I must say i love the comment about theyre nuts must vibrate like cell phones.. i git a good laugh. I love funny youtube comments, and then idiots who buy into it like you are just slightly less funny.

[xbull123]

wez nie pierdol

[Hexpigge]

well it would be cool to have one of those magnets at home :D... pretty cool :)!

[angweeshuen]

lol. it will be damn dangerous.

[Hexpigge]

danger = fun, but... :D only 50% of fun :D
