fun with science

[alien42]

i will have to try this when i find a magnet.

 

[CraKaJaX]

Haha, sweet. Is that the same kind of magnet as like, an earth magnet?

 

[So]

Sweet!

 

[SonnyDaze]

That's cool. I'll put that on my desk and get 😕 looks. 🙂

it doesnt appear to be a rare earth magnet in the video, not strong enough.

Neodymium magnets are rare-earth magnets.

I've seen that done before. However with a little extra work you can actually make a DC motor that works like in real life. Theres a good video if anyones ever seen it of a gatorade bottle with 2 rare earth magnets used as the rotor of a DC motor thats pretty cool. Just add a coil with alternating DC currents to attract and repel the magents and boom it spins around.

thanks!

i just purchased a grab bag ($15 + $7 USPS priority shipping)

Yep, cool. Doesn't necessarily need a neodymium magnet though. Do a google search for "simplest motor" - it's a common science fair or class type of project. I've seen contests where kids make their own in class. The contest part is "whose will run the longest." All brand new batteries from the same pack to be fair. (And a camera to take pictures every minute or so overnight.)

Yes, the pictures work; if it's moving, you can tell from one picture to another if it's in the same place or a different place...
