Homopolar motor demonstration

[baldurus1]

Hint: Don't try it with a magnet with a lifting force of over 200 pounds.

The magnet weighs over 100g and when you get 100g spinning at 15,000 rpm=disaster.

[Zazay613]

hey can someone please answer my question willl this power a car (toy)

[24cat11]

How ido I do that

[DanielTseng100]

i maked some sparkles but, 0 spin

[Autocoche023]

Excelente video

[fleamau]

why does my screw keeps turnig into gold?? >.<

[lrojasma]

@fleamau Maybe do you have a golden making machine :)

[elloboclon123]

algiuen me puede decir que se quiere demostrar con este experimento

[antoninodemachu]

wow nice.. no dont have to worries on joint driving shaft, good work

[ek451]

does anybody elses get stinky?

[MrTabat24]

I'm having difficulty making the magnet/screw spin. It'll only spin half-way around and then stop. Are there any suggestions as to why this is happening and the motor isn't working?

[oskay]

@MrTabat24 Motor or battery is too weak, or perhaps the magnet's coating isn't metallic.

[gamarralm1]

oooooooooo ese experimento voy aser ya q se dice q algunos no le as salido

[gaypotter]

lol homo

[DontPressA]

Look theres a powerful magnet on the screws head magnetizing the nail you dim wits

[fireballproducti0ns]

How do you get it to stay in the battery?

[Protection220]

FIRE IT AT SOMEBODY

[factiz501]

The title is asking for it

[TheBurnout222]

i did it

[Geminii27]

Hmm. Use a hammer to drive the screw point a fraction of a millimeter into the top of the battery, just enough to make a barely perceptible dent, and the screw might drift about a lot less when it's spinning. Or would constraining one end of it make the other move more?

[alkon6989]

gran aporte..



[Specterjobin]

0:08 Watch as I magically turn this screw into a nail!

[jaimetronki1]

que es eso que l acercas

[TukisHunter]

manyak bişey =D

[MrFingersniffer]

why is this motor popular with homos?

[kevinsillo100]

el cable en donde lo conectas

[iani103]

Huh...

Homo...

xD

[SrAlan1121]

Bue-ni-si-mo!!!

In english: great!

[lindaluna213]

que genera el movimiento giratorio del tornillo

[qwertyjake1]

it burnt my finger

[truchowski]

everytime i try to do it the copper sticks to the magnet and yeh i cant do any of thoes magnet tricks idk why :(

[oskay]

@truchowski Copper isn't magnetic. If your wire sticks to the magnet, it may not actually be copper.

[truchowski]

@oskay oo my teacher probably gave me the wrong thing haha ill try again soon thanks :D

[THEROLLINNGDICE99]

@oskay when wires have an electiric current flowing through them, they produce a magnietic field. Which if strong enough can produce a slight "stick" to the magnet

[dmerozie]

why does it spin



[DifferentKev]

Das hab ich auch mal ausprobiert und hab damit über 'ne Stunde rumgespielt. o_o

aber mein Magnet war nicht so stark, bei einer bestimmten Drehzahl ist die Schraube dann runtergefallen.^^

War ein Magnetstück aus einem Geomag stab.

[life6241]

I thought Polar bears were straight :'<

[digerydooboi]

who's blood is that on the wire?

[senseTUBE]

it works best with rare earth strength magnets

[cornesicosi]

i think its not a magnet.. i think it's a bateri

[suckerfreelatino1]

can u use any type of magnet that size and any screw?? please reply

[onlYzcW]

Great !



[kurisu925]

Next time use a drill bit instead of a screw.

[MrGimli2]

lol homo power

[pulsedrop]

how efficient is this?

[Sisound]

haha homo

[RockIncProductions]

Make a video on how to do that.

[sailboard511]

If this thing flips out, that can make a reason for death.

[massine10]

fucking magnets, how do they work?

[troyger1]

how u stop i ??!

[fulanita858]

que tipo de cable se usa??? algien qe responda mi pregunta xfa

[Masowai]

@fulanita858 Puedes usar cualquier typo de alambre. El secreto es usar un iman con un acabado conductivo. El corriente necesita pasar del "mas" atraves el alambre, iman, y tornillo, hasta el "menos".

[diffan666]

HOMO!!!!!! lol the thing is geeeeeyy!!!!

[simeonhaha]

@diffan666 Mostly those who call someone HOMO , are just that.That thing is not "geeeeeeyyy" learn to type gay..also if you don't like it go to your homo friends and start "homoing"

[antoknioD]

what type of magnet are you using?

I want to make one for my kid and isnt working.

[oskay]

@antoknioD NdFeB; it needs a disk magnet magnetized through the thickness and a conductive coating.

[ivandonat]

@antoknioD

Easier to say, Neodium

[happygamestvfun1]

@antoknioD edit: you want to make one for yourself but are to embaraced to say so...

[420jitender]

I want to download video

[nikulp68]

nice demo of maxwell's screw rule.

[richiparada54]

wea loka

[Mataxiviri]

la wea loka xD

[jamesclements997]

neat

[daDJnaga]

omg thats cool

[DulceSakura06]

Orales ahora entiendo eso de cuidado con los ojos ^^

[Taydrum]

LOL HOMO

[flakgun153]

i can't get mine to work. the only difference is im using a smaller magnet. but it should still work right?

[ashish19]

well, the magnet has to be powerful enough. This guy must have used neodymium magnet

[CRFbadass]

OMG THATS TERRIFYING!! D=

[vkonovsskateordie]

it'll be cool to install that on an rc car

[coder0xff]

Good way to get a very hot wire and battery.

[diffan666]

great job! but what would you be abe to make out of it?

[freedme1]

A toy car that moves WITHOUT touching the wheels

[wellwisher106]

dude, think positive. it's just a video to demonstrate the mechanism of motor (for the people who are not engineering students like me)

[deathgp]

what type of wire is it

[dypelb]

америкашки говнго

[oOFREEKILLOo]

i dont know mate i only know that is the nedodymium magnet(s)

i saw it in a other vid

[oOFREEKILLOo]

nedodymium magnets

[fargus5000model]

it looks like a nail when its spinning fast

[nw5production]

that is an electric motor

[intheshitter]

How efficient would this kind of motor be compared to the other electric ones?

[chickenpoper]

it floats o.0

[FreakExceptionale]

@chickenpoper There is a magnet at the end of the screw.

[ArdyCakes]

AWESOME!

[orawec]

to znam tohle se mi taky povedlo

[sp00nix]

Would a current limiting resistor be a good idea to keep the battery from draining so quickly? That is so close to being a hard short lol

[mrtla69]

hollow magnet with lithium inner core. the magnet will rotate to power a alternator / generator witch sends part of the power back into the

lithium inner core. this power the magnetic field making a electron magnetic with a lithium inner core witch spins the device faster. [=] more power..

if this adding power to the lithium core, it might cause heat. hot enough with a sentricular force can cause anything to occur in a powerful magnetic .

[MrSexyboom]

= = ~ the 2nd one is more ... funny ~ lol

[alx033]

haha yeeeaah!!

[fluffynekonate]

it doesnt work for me and im doin it like it says to

[jodex96]

This is cool. I recommend trying. Just a battery neosymium magnet screw and a piece of wire..

[LacrosseMaster66]

r the magnets a special type of magnets or are they like most magnets?

[intelligentjackass]

They're called neodymium magnets, or sometimes rare earth magnets, some people call them super magnets. Just look it up online to find a store, or buy some off ebay.

[kocbiyik]

electrically commutation...Cuz of cros sectional are is big that current flows trough...

[laputahayom]

starts drilling it to the battery.lol

[antgrav]

lol

[OverThatKid]

It's going the wrong direction to drill into the battery

[pakmandan]

it spins the other way if the magnet is turned upside down

[JippyJack]

Its was a joke genius

[DreadMauler]

@OverThatKid no it's drilling in, not out? the crevasses are spiraling upwards= drills into the battery.

[93Wakizashi]

@OverThatKid turn ur magnet around=P

[rmullen]

you would need self tapping screws lol

[javigutz]

chupalo

[bellend181818]

BUT WHO WAS PHONE?

[FUTTAHSIKK]

haha i just lol'd

[Maticus2009]

Apparently it was a newfag.

[santiagokof]

eso es facil lo hice en la prepa

[a4finger]

the screw HAS to b feramagnetic?

[SheerPandemonium]

Well it has to be if it is going to hang from the bottom of the battery. But for the homopolar motor to work, all it needs to do is conduct electricity.

[netenute]

Deberían arrestarte por escribir asi.

[bugsbrunoCP]

???

[Mindofpoet]

if you dont wanna spend money like me i would just take apart some old headphones and there you go

[BlueBajs]

You think that wires are expensive?

[koenie12345]

i think hes talking about the magnet

[CHACHUBHAI]

btw, wat is the simplest house-hold material which contains these neyodium magnets...

pls answer,thx..

[robbieisbadass]

does anyone know what stores they sale neodymium magnets (in usa)

[BuffaloWarrior7]

raidoshack has them

there over priced though...look on line get them in bulk for cheep.

used them every where.

[space922]

i bought some for radio shack for 2 dollars but i think i got the wrong one its really small and the regular size of the battery and idk where to get the bigger size one

[SkyWolfmetal]

you can take magnet from headphones too

[PlasticPackage]

Hey look, an owl.

[morspaceman]

what

[LOSR10]

ke es esto?

[kerog6]

huh huh homo

[walikai]

lol looked like a lamp in the preview

[nawara88]

Nice

I tried this but it didn't work, may be because i used non- neodynium magnet or what, help????????????????????????

[HalfBredNinja]

It doesn't appear to work with anything but a neodynium magnet. Even if the magnet conducts electricity, it seems to provide too much resistance for the magnetic field to be created.

[error4385]

it needs to be neodymium. also make sure the battery ain't dead.

[nawara88]

thanks all

[vanesa4831]

1. Aguanta la respiracion

2. Copia este comentario

3. Ve a otra pagina, con un video diferente

5. Vuelve a respirar

Si puedes hacer esto sin respirar en el proceso, significa que eres un buen bezador

[zscagr]

besador?

jajajaa

[JaedomHexen]

HA! Cool I love physics, this would be gret for school kids to learn remedial electromagnetic rules like lorenze force hehe the magnet was in a great position to demostrate this idea. :-)

[ramiboy99]

im confused =O my physics teacher told me that a "homopolar" is impossible =O wtf is going on

[gauravdawg]

hows the nail balancing? pretty cool

[IAlmostEnjoiSkating]

its not balacing, its hanging

[datlildodge]

i meant to say on the "battery's" positive terminal

[datlildodge]

okay dude, you can make it by:

you need a battery, a neoydimium magnet, and a copper wire

place the magnet on the nail and stick the nails point on the magnets positive terminal.

now place a copper wire on the negitive terminal and the other end on the magnet.

it should spin

[Silverthehedgehogxx]

Lol HoMo. I didnt call u 1 im just immature.

[sup1223456789]

Can this work with a smaller battery?

[RamoneTalarico]

i did this with a car battery, but holding it up KILLED my shoulder

[maherosman3]

how do i build this can some ome tell me step by step

[DuttonWebb]

dude. just look at it. are you retarded?

[spider6837]

i just made one like this except my magnet is bigger and it is a whole lot slower

[MattyH101]

its all fun and games 'till the screw drills through the battery

[Downbeat1984]

i believe the magnet produces the electricity by the coils of the threads on the screw which causes induction

[oskay]

>i believe the magnet produces the electricity by the coils of the threads on the screw which causes induction

You forgot the part about the virtual flux capacitor induced between the battery and the wire.

[magemager0]

ok then....

can sum1 tell me what the magnet does to produce the energy

[mvlady]

NO never

[NEEDCARS]

yeah... No never

[RCScubadiver]

you seemed nice...

[hammyboobs]

this isnt my account. dumb hammyboobs is my brother i just use his. im the evil one ill fucken kill your motherfuckign dirty bitch ass

[Ridson1]

this is a real lab u mooks he is a real scientist and that is realllllllll

[Hyper6664]

??????

[241Groundhog]

An explanation would have been useful.

[hammyboobs]

he just gets a simple coper wire and tapes it on the back of the battery and get a simple dry wall screw and tape those itty nittyy batters to the back of the screw and toch the other side of the little battery with the other side of the wire

[theincrediblenoone]

a magnet in place of the button battery in your explanation better explains why the screw hangs upside down...

[hammyboobs]

yayyaya whatever... im no nerd

[elcko123]

you try to act like one.. -_-

[hammyboobs]

why the hell would i wana do that..... and how am i acting like one????

i just know what he did moron
