Homopolar Motor Version 2 - Sick Science!

[luirive]

That is a copper wire right?

[perkypears]

how it works is the gravitational force of the magnet and the energy from the battery conflict because they are both positive energy so it tries to push away but it just spins and spins

[2000KamranKazmi]

where do u get those magnets? i have them some magnets but they are way thinner

[valzilla2000]

no homopolar

[spartan7126]

how to drill into a battery

[MCSniper122]

wont the screw dig into the battery and explode it or make battery juice leek and be bad for kids?

[5216l]

@MCSniper122 no, its not strong enough to dig into anything

[coolgirl482]

where do u get the neodymium magnet and the led lights from

[chri600w]

thats what i call "screwing around"!

[brianyehvg]

an AC battery? batteries are dc...

[puiselo]

@brianyehvg are you stupid? :DD no offence... but it means a "C battery"

[Paradoxer411]

@brianyehvg as in one "c" sized battery is what they meant.

[SuperPoketown]

its because the battery is a energy source for it to work. the wire helps " guide " the electrons to the battery and thats why it keeps going. the electrons will know where to go to so they go down the screw to activate the light

[iRuss876]

SO COOL XD

how long does it go for??

[12Edix21]

@iRuss876 until the battery ends :)

[DonatasIsAWESOME]

i like trains !!!!!!

[coolgirl482]

what kinda wire do we need

[jacobblack18]

@coolgirl482

copper since it's one of the most conductive and cheap wires out there.

unless you have gold wire xD

[johnnyjagged1]

ac means alternating current

[supaZarrin]

Did anyone else just started smiling when the magnet start spinning?

i think its just me...

[FLUKE841]

AC BATTERY ??????????

[MindofScience3]

@FLUKE841 A C-BATTERY (as in C-sized).

[shade476]

0:52 i was expecting an exploson :(

[alsalamaleykum]

I think, first you must know why regular DC motors need collector to work, to be confused about how this thing spins at all?! In addition, all electric and magnetic field poles placed on same axis: how their lines can cross in principle?

The answer is: magnetic field lines cross wire from inside the battery in radial directions. So we have a Lorentz force perpendicular to this intersection, which pushes wire in tangential direction around the battery.

[alsalamaleykum]

I think it work's like homopolar motor.

No need current commutation to work!

[ihateanime123]

Simple the electricity travels through the wire to the magnet causing it to be constantly pushed in a circular motion then the batery connect to those the eletricty via the screw and makes a type of circulation of electricity expect the electricity is used by the magnet and then (for lack of better words) is dissolved. correct me if im wrong

[gomezpiro]

Cool !!

[123456789kamran]

can you stick another screw on the magnet to make a screw driver?

[peterrocks301]

Great, now i have to find ScienceExpirimentz comment!

[guyinhoodie]

@peterrocks301 great now I have to find scienceExperimentZ comment

[AutoClubVTEC]

conclusion? OMG its witchcraft !!

[rlstinefan1]

cool

[PhoenixxGHLG]

Conclusion: guy in video has hot body.

[brokentrigger1]

i like the other background music better.

[3xtralife]

Sick!

[Alexia101807]

this is so cool... where do i get buy that magnet?

[jawsextracted]

@Alexia101807 from the shop

[TheAndroidNerd]

@Alexia101807 u can order them from a place called dealextreme

[Alcidix12]

Hello Steven!

[mynxiejynxie]

Will it ever drill a hole in the bottom? Isn't this kinda dangerous?/Fun.

[masterchif7]

cool video it atuily work

[DancerS84]

Thats kinda cool

[Prepasbeats]

kewl



[Lrzq]

omg, this is epic :D

[j2avV]

hehe homo.

[luisluvsblastbeats54]

lets see kip kay do this

[XTwisternickX]

@luisluvsblastbeats54 he already did.....

[ThelDinko]

now just power a car with this

[thegreatflyer1]

who like pie?

[thegreatflyer1]

thumbs up if u like pie!!!!!!!!!!!!!!! >:0

[TechnologyMe]

Well, I think the Neodymium magnet can conduct the electricity,The screw just probably connects the the negative side to the magnet. The wire touches the positive side,therefore electricity travels through the wire touching the magnet making it spin.... Again Im not sure about my conclusion.. PLEASE REPLY STEVE!

[LetsGoRiotThisBitch]

Science is AWESOME!......except in school

[DarkHarpuia]

Wow, that was really neat!

[MeriLuvsU8]

HOW IS THIS SCIENTIFIC LIKE WHAT KIND OF ELECTRIC ENERGY DOEZ THIS CAUSE

[grimbattalion]

How long dose it spin after your wire is removed? It looks as if it keeps going.

[Sp0tt3dl3af]

@Stevespangelerscience I already know what u look like. ;}

[xquisitaz]

Hey guy in the videos! I could think of a few practical uses for this motor but I know little about it. What is your thoughts....can you share with us what kind of cool things kids or adults can do with these motors?

[FMBAir]

So what I think is happening is that the current induced in the wire creates a magnetic field which is perpendicular to the magnetic field of the magnet, producing torque on the screw/magnet setup.

[DutchKid121]

hah! he said homo :D

[panzuman]

but that battery is dc not "a c"!

[CloverFuchs]

@panzuman It's a battery with the identifier of 'C', as opposed to 'Double-A' or 'D', etc.

[thegaga2u]

cool



[thegaga2u]

cool

[VividnessProductions]

This looks so cool ^_^!

[S2happy44]

OMG THAT'S SO COOOOOOOOL

[spicysushi1]

do i need that specific magnet?

[SodhiFamily100]

its been a month, put a new experiment already

[TheNightmare2021]

I think this happens because the combined electricity of the C battery and the watch battery moving through the wire and on to the screw cause the screw to move in a circular motion due to the grooves on the screw thus spinning the magnet and L.E.D lights but can the homopolar motor be used to power a childes toy

[cliftzchel]

now i have a toy for teens or adults

[TheAllBlackMan]

Could this also be done with a nail? Or do the grooves of the screw have something to do with it?

[TheClassicOriginal]

Can you please tell me the dimensions of the magnet and the clock battery ?

[ThirdSon13]

an AC battery? where do I get one? lol 

[ChioNeal]

does it drain energy from the battery as it spins?

[Stevespanglerscience]

@ScienceExpirimentz

That would destroy the fun of people not knowing what I look like!

Sincerely,

The guy in the videos

[slimshady8252]

@Stevespanglerscience who doesnt know what you look like

[warriorfandude]

@Stevespanglerscience one look at this and the morning cup of coffee ruined my computer U R TRULY FUNNY

[MegaActionFigureFan]

@Stevespanglerscience Ha Ha good one

[Mrjoecreeper]

@Stevespanglerscience Do you still look the same in the news forcast videos? or slightly awesomer?

[MCboburnham]

@Stevespanglerscience where do u buy ur LEDs from, i cant find any LED diodes that are at least as bright as a MAG flashlight

[ihateanime123]

@MCboburnham take them out of a flashlight

[mhultraa]

it would be better if he didn't wear a blue t-shirt

[rubenflush]

This is awesome

[MissMusic2416]

Thats coolz :D

[rolicolopon]

will it drill a hole in the magn3t?

[AlistairAI]

This is science, a smart and technical explanatory demonstration

"IT JUST LOOKS SO MUCH COOLER WITH THEM!"

[Semtexxxxx]

When a light-emitting diode is forward biased (switched on), electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electro-luminescence and the color of the light (corresponding to the energy of the photon) is determined by the energy gap of the semiconductor. OMG.

[SodhiFamily100]

hey can i order a neodymium magnet from the website

[22Chrisie]

This is my favorite video!! =D

[22Chrisie]

Stevespanglerscience Once on ellen you said you came from a family of magicians. Did your parents teach you sience?

[KurogetsuOokami]

@22Chrisie His parents have been involved in science and physics for over 35 years. They taught experiments in the form of fun to elementary school kids. Very cool people.

[jediboy96]

could you hold the magnet and do the whole thing reversed? i.e., make the battery spin instead?

[Mrmoonboy5]

all fun and games till the screw goes through the battery and spills acid all over your hand

[blva888]

@Mrmoonboy5 Yes all fun and games and when the acid spills than its hilarious.

[KaiHiwatari7]

Imagine there was no gravity, and if it was turned upside down, the screw would go in the battery, haha.

[jediboy96]

@KaiHiwatari7 with no gravity, there wouldn't be anything pushing the screw into the battery...

[Jerrycobra]

woah best one in a while

[AkumaNoRobin]

DoDoDaDa music made the science more funny and cool

this music make the cience more...bored :|

[thundrusaqw]

then put another screw to make a EPIC DRILL!:D

[HoneyIShrunkTheKids2]

how did u figure this out?

[SumoSushiHAI]

That's a piece of scientific sweetness right there!

[1000jamesk]

I think he didn't use the DoDa song on this one because the video is too long for it, and it would make it annoying.

[MagicDiner]

Now that's awesome!

[kfdamian]

I love the music on this one. makes me think of tea parties, cauldron cakes, and sunshine. gosh I need a life!

[6158bubbles]

pretty cool!!

[6158bubbles]

thats crazy sick cool science

[6158bubbles]

thatss soo awesome i love science

[6158bubbles]

thatss soo awesome i love scienceee

[screamineagle88]

Does the magnet slow down after the wire is taken away? In the quick clip of this video it looks like it just keeps going.

[ojik]

@screamineagle88 Definitely, the closed circut on the top, makes the bottom part spin. When you cut off the electricity just inertia keeps it going. It wouldn't stop, only if you were in vacuum.

[rainfop]

where do you get a Neodymium magnet??? i want one :D

[rainfop]

where do you get a Neodymium magnet? 

[scatchntrance]

this was cool!

[manneke150]

Magnets, how do they work?

[fly12f]

If the speed kept increasing, would the screw eventually drill through the battery?

[iSoMuchWin]

@fly12f no.

[1000jamesk]

@fly12f No, because you have to apply pressure to the screw for it to drill.

[HEKODON]

HEY!

[fongv2]

The one who disliked it was the one who couldnt make it...>_>

[sweettooth80]

awsome!!!!

[jayghan]

whoop whoop

[jozydee]

that was soo cool :] liked it gonna try to make one myself. thanks

[KWizzle38]

turn off the lights!

[Clayton2MacDonald]

All of the materials have diffrent static charges some our neutral some positive and some negativee all causeing some to attract eachother while others are repeling.

[RatkoUSA]

Wow, nice homo motor

[rolicolopon]

that is awesome

[TheKillerScorp]

lights are moving? io vgues..

[anitasangel]

finally something interesting

[TheDannyboy214]

Still cool do

[kettech16]

new music!

[vlogboy209]

Wow these science projects are really cool and easy to do.

[sasukeichigo12]

15 led's and you got yourself a rave! xD

[CuateGolden]

I've been going for years to all the stores here in my city and I just CAN'T FIND NEODYNIUM

[lemonadeloverz]

does it have to be a special magnet or just a normal one?

[J03Y13]

Even better! :P

[whothehellisthat]

wow! that was cooool! but what the hell is a NEODYMIUM magnet?! And where are we supposed to have those lying around?

[hilariousguys]

@whothehellisthat It's A VERY Strong 'Earth" Magnet. I Picked One Up At Princess Auto For A Previous Science Project. I Have Never Seen Them At Walmart/BestBuy, Etc. More Or Less Only Available At Hardware (ish) Stores Or The Internet!

[hubertandclyde]

@hilariousguys Why do you capitalize every word? Seriously, I see people doing it and I am just wondering why.

[edog355]

@whothehellisthat you can buy them at hobby stores, there are rare earth magnets, extremely strong,

[FNEIN]

@whothehellisthat A Neoydymium magnet is a special rare earth metal that is the strongest magnet the public can buy. You can find them anywhere in hardware stores, or on the internet.

[anyone584]

Why do people see the DoDoDaDa music as their gods? This is science, not music. If you really, really want, I can't make a 15 minutes loop of the DoDoDaDa music.

[Tobynator1]

@anyone584 make 57 min loop plz

[Thankots]

@anyone584 You're kidding right? It is just for fun, the music the comments..

[j510t]

@anyone584 no one mention the song besides you

[MmeJulll227]

@anyone584 Make it Make it MAke it :D

[hubertandclyde]

@anyone584 Why can't you?

[HellsingWalter87]

@anyone584 Its not like it's a "god" thing. Its more like something one comes to expect from watching Steve's videos for a long time. You get used to the Do De Do music and when you don't hear it, it throws you off a bit.

[RoachSanderson]

@anyone584 I WANT!

[salrubz]

@anyone584 please do

[Squidnibbley]

@anyone584 Would you?

[katrin6789]

@anyone584 cus the music owns

[pmasterp900]

@anyone584 PLEASE someone tell me what song this is!

[kyrectx2]

Black Magic of course...

[fightmegirl]

This is so cool!!!!

[icyshadow0]

@susanbasnet Well, i'm serious... o_o

[kyle110438]

first dislike!



[Ozzy2Rocks]

@kyle110438 thats honestly nothing to be proud of. just saying

[DudeMan636]

@kyle110438 still only dislike.

[AfroNinja720]

lol sweet
