Lec 21 | MIT 8.02 Electricity and Magnetism, Spring 2002

[willbirful]

great video thanks

[Kricardose]

Good, I like that you share this video erromagnetism Prize Ceremony of Motor Contest, I wish success always

[bebeheuy]

I Love The Video It Can Increase My Knowledge Para, and Ferromagnetism Prize Ceremony of Motor Contest

[Mjhond]

Steady I Really Like This Video Para-, and Ferromagnetism Prize Ceremony of Motor Contest

[PaulaZulmatu428]

lol is ja lustig

[sandslash123]

Actual lecture starts from 6:00

Thumbs up so that others wouldn't waste 6 min of their time.

[vivauruguay]

HE LOOKS LIKE THAT GUY FROM BACK TO THE FUTURE

NEVER THE LESS HE IS A VERY GOOD TEACHER ONE OF THOSE WE DONT HAVE ANY MORE IN ANY UNIVERSITY

[agapitoflores001]

Very electrifying! whooh.. excellent lecture.

[1PeaceNation]

he is really really good.

[TheFaceOfJohnPants]

0:54 he's a player

[raghbendrat]

It's mesmerizing. !!!!! amazing power to captivate the listener !!

[Stratocaster1111]

Asian pride!!!!

[kotofu]

every time he changes the lights, its like he's playing piano. Really looks like a maestro :D

[CaptainChaos]

I think I recognize my own accent there... Anyone know who the prof is and where he's from?

[ingoboris]

@CaptainChaos walter lewin, dutch

[CaptainChaos]

@ingoboris Thanks. Yup, a fellow countryman. :-)

[Ferrus91]

Best explanation of a permanent magnet on youtube.

[aditraj]

@kkali33: you measure the rpm using a tacometer. i think.

[kkali33]

does any one know how to measure the rpm of this motors?? with which instrument or something?? it is for the one I built, thanks

[shimgoody]

Yeah so I'm like sooo mad theres no quick scoping in black ops anyone else?

[stephencooldog]

@shimgoody lol ur random 

[KingCorvette]

Oh god this looks so awesome, I wish I could understand half of what he was talking about.

[Coffeevaccine]

I want that thermometer.

I would carry it with me to the gym and exercise with it.

[panzarw]

that winning motor was so simple, i thought they made some like heavy duty ones, massive coil/magnets.

[1V10ntyPyth0n]

<3 these lectures! it´s sooo great, plz do more courses! :) Mb ill go to MIT some day (hoping for a exchange program or something ;))

[warriorsquest]

I am amazed that the fastest motor made no improvements to the basic setup that he described in the handout. (from website) I'm convinced that if I was using the same materials, my motor would leave her's in the dust.

[warriorsquest]

Does anyone know the specs on what was handed out in the motor kits? I built a motor which I think is a much better design than her's, but I think my magnets are much smaller than the one's they are using.

[IronChefWannabe]

ha ha, her reward was extra homework

come back next week and explain how the thermometer works

[TheKungenKing]

Please record in HD! And upload in HD!

[LogInForPaper]

Is this a physics lecture for engineering students?

[Lockemeister]

Did he say he was having her over for dinner ? More kisses ensue.

[IronChefWannabe]

he said 5 winners, group dinner

[tonyrosam]

hey is it possible to make a device that feeds off a large radio wave spectrum that could fit in a garage?

[ZZ2SVA]

This is already old, the new engine will not need energy magnet motor, the future George 2010th

[decay789]

what class is this?

[teledynepost]

@decay789 MIT 8.02 Electricity and Magnetism, Spring 2002

[IronChefWannabe]

decay789,

read the title of the video

[decay789]

lol thats the class name? oh. thx hee hee

[Spoodily]

He has McDonald's french fries on his shirt.

[Ranjana95]

did anyone really watch the whole thing???

[VerbalIronyX]

Yes, I watched the whole thing. I'm taking the class right now at a different university and the videos help. They are using the same book and he follows the same schedule my professor does.

[polarbear60]

Kissing a student, not a good idea.

[amerthil]

look how enthused they are by nothing in like the first 20 seconds.... FUCK mit kids.

[case12hdsybncjkd]

You are just a ray of sunshine on a rainy day. What excites you? Wimp.

[psychobollox]

this is supposed to be a lecture but he's actually _teaching_ andit's amazing to see his own excitement at what is happening with the things he demonstrates!

this guy is CLASS!

[ShinmaRyuu]

22:01 How to make a rail gun 101 :D

[bucles2000]

Quantum mechanics to understand diamagnetics materials?..There is a circuit in that materials when you induce a magnetic field it produci an Eddy current that also polarize permanently atoms creating permanently and opposite magnetic field.

[goodluckpeace44]

well that sounds valid,

[BenZeneProject]

That was Awesome!

[Ironman1960]

I wish to had this kind of teacher during university.

Fantastic!

[Saskachewan]

The best I have ever known.

[fastcarss19]

really good teacher
