Homopolar Motor Instruction Video

the wire isnt supposed to toch the magnet...

[lawsonfulton]

Then where does it connect...

[lawsonfulton]

1. I think I found it in my basement. In a drawer.

2. $1.45/lb

3. Some random neodymium from lee valley.

woohoo, i get to calculate the torque on my EM II exam on friday

[freakstupid11]

crap 33000 views..got some work to do now... i don't believe thats you i'm gonna have to see your fingernails tomorrow to prove this video hmmph

[lawsonfulton]

AHAHAHAHAHAHHHAHAHAHAHAHAH

:|

[tr0s3ph]

OMG.. this is so fake your obviusly usin black magick to do dat

This is actually pretty cool. I'm building one now. :)

[frankwilliams987]

you can just strip any old wire (i.e. power cord -make sure it's not plugged in lol, headphones, etc.)

the best is an old phone cord since there's 4 separate wires inside that you can use.

[lawsonfulton]

You could do that, just remember the wire has to be adequately thick to bend into shape. Preferably more thick then what I used.

[jorecm]

does it have to be that kind of magnet?

plz reply

[lawsonfulton]

As far as I know yes.

I don't think any other type of magnet is strong enough.

They are very cheap to buy and they are a lot of fun to play with :)

try ebay for starters.

[hyperTanker]

simplest

lol

[lawsonfulton]

wha?

[hyperTanker]

watch this> youtube(dot)com//watch?v=Xnxf1­WeXxgk

[lawsonfulton]

what about it?

[9ur3mines2]

where can a 11 year old get some copper wire?

[lawsonfulton]

hmmmm well if your dad or someone you know has a like a workshop or something you could try there. just make sure whatever you do the wire is thick enough to hold a shape.

[lawsonfulton]

lol

[mickeynotmouse]

heheheh, a gay motor. ^^

[inad316]

ok question. i know its spinning cuz of the magnetic fields and not using the battery. but is the battery getting drained, or no?

[lawsonfulton]

yes the battery is getting drained and fairly quickly at that. do a google search on homopolar motors and you will find out how they actually work

[STOPnTHINK]

yes, there is a polerization made when the electrical feild amplifies thru the dc, current.... it is the magnetic feild of electricity around the wire, that is attracting it towards the magnet in a spiral effect ( note , the eziest way nrgy seeps into a core is with a vortex. The vortex of the magnet, and the wires magnetical feild make elecrto magnetical attractions ) etvoila , ur answered

[karlontxo]

after watching 3 videos i can say yours is the easiest one, congratulations!

[lawsonfulton]

thank you

[AnDr3wYoN]

man ur horrible at bending copper but good job on the vid

[lawsonfulton]

The copper I had was to short so I had to put 2 pieces together and it was a very thin and flimsy bit of wire. But it was still mostly my horrible copper bending skills lol
