Build your own ultra-simple electric motor with only a battery, magnet, safety pins and a bit of wire. Takes only a minutes to build, but will keep you mesmerized for hours. Cool science project. Impress your friends.
How do you get the coil to keep spinning if you completely remove the enamel from both sides of the wire? I would think the coil's magnetic field would simply alight with that of the permanent magnet's and just sit there. In order to spin the current through the coil has to stop for at least half the cycle.
Hey thanks loads for this!! It's just the kind of thing I'm looking for, for my ten yr old home schooled son : ) Many thanks for sharing!
same here, great demo for kids
<p>where could i get 1 of those magnets from?</p>
what song is playing in the background<br />
Would a penny with copper wire attached work?
You forgot to mention one requirement : Gravity :-)
I don't know about you, but I'm not planning on going where there's no gravity any time soon. ;-)
Guys! I was just pulling the leg for fun! Thats all.
eh, mate, don't worry 'bout it. i was kittin' too.
I'm with you.
Why do you need gravity?? Just to keep it on the contact points?
the video is getting so annoying because it dosen't load fully it keeps on stopping and starting i wish he just had some flipping instructions
I tink it's your computer, sorry mate. It didn't do that for me.
THAT'S COOL DUDE!!!!!!!!!!!!!!!!!!!!!!
thanks for giving such an opportunity
Any photos or stills from the video? I am no a connection that can not view streaming video, not because of the lack of bandwidth but the fact that the service I have is so crap, most I get os about 108kbps average on a service they sell as T1 over 3G/HSDPA connections. So some stills would be nice to see.
Awesome! ill try this with solar cells :)

What type of wire did you use? Would that green craft wire stuff work too? Because yours is copper, and I think the craft wire is something like aluminum, or zinc.
i know you commented a long time ago but in case your still wondering and didnt try it out, aluminum should work. not sure about zinc though as long as the metal conducts electricity.
ok, thanks, il try
Is there a desired amount of winds you need to make? It is a great project, thanks a lot.
ca it be any type of magnet?
I love this. It's easy. Anyone could make this. You could make this into a desktop fan perhaps! And use a rechargeable battery. I have some scrap copper wire in the house from some renos. Would that work?
THANKS SO MUCH. I need a science proect and this is perfect. GOD BLESS YOU!
