- Low cost: If the project is going to cost me a million dollars (exaggerated a little bit) I won't make it.
- Easily accessible materials: If the materials are impossible to find (unless it is a really, really cool project) I most likely won't attempt it.
- Usage: What will the project teach me? What experiences will I take away from it? If I had students, what would this teach them?
- Simplicity: If the project uses 6 integrated circuits, I won't even try. Most likely, I will try to find a way to make it with a microcontroller. If nobody had done the project before with a microcontroller (unless it is really good) I won't try.
However, of all the tutorials I had looked at nobody had made it simple enough so average people could do it.
This would be great for classrooms because it teaches magnetism. My science teacher had one but he plans on getting more soon. It is small, cheap and easy.

1 Neodymium Magnet (This is probably the only part you will need to buy unless you have an unusually large junk parts parts bin.)
2 Safety Pins
3 Feet or 1 metre of 18 AWG Magnet Wire ( I used 18 because of its thickness and stability. It is a bit harder to work with.)

Cotton Ball

Thanks.

If that makes me sound like an idiot dont be to harsh im not really that great with electronics.
I just wonder would that much power make it stronger?
Problem is:
A: Where are you going to get the power?
B: Even if you do get a hold of the voltage, you are shorting the battery...is that safe to do?
If you plan on using an AC outlet I suggest you don't because it can cause fire if shorted.
Typo, but yeah bigger magnet, Thanks!
Or since you use a rechargable battery use that and you'll charge the battery when the coil is rotated. Theoretically anyway. Realistically, you probably won't generate enough voltage to charge the battery.
But in a practical sense, you're probably right anyway, in this case. I don't think this apparatus acting as a generator would be able to overcome the force provided by the battery.
They use one way bearings in wind turbines etc.
It is magnetizing the outer coating of the battery,
which is why the safety pins are sticking to it>
Think outside the box
:)
I didn't read all the comments before
But if anyone wants to build a real simple motor, they can build one with a "C" or "D" battery, a short length of wire (about twice as long as the battery), a neo-magnet (round), and a straight pin.
All they have to do is set the straight pin dead center of the neo-magnet and suspend it from the dent in the negative (or -) end of the battery (It should hang there magnetically). Then take one end of the wire and hold it into place at the battery's positive (or +) with one of the fingers from the hand you suspend it in the air with. With the other hand you very lightly touch the side of the magnet and it will start spinning. And btw, if you filp the magnet over, it will spin the other direction.
It might be a better visual if you draw a line across the magnet with a marker or something, but I would worry about breaking the conductivity of the pin. Maybe just a dot or two on the face?
Also I didn't have much of a problem hanging the pin/magnet combination from my battery, but if you do, you could think about snipping the pin to shorten it, or use a stronger magnet.
Pretty neat demonstration. It'll give you something to think about! I still haven't got my head around how this works.
Sorry for the long comment. I might have posted it here, but I don't subcribe. Thought this was a good place for it.
Good instructable!
It's safety pin by the way...
As I said in the comment over the second safety pin, I did magnetize the pins. Thanks, though.
Do you really not speak any English?
Would it be ok to just make a quick frame to support the magnet next to the battery?
Also, no need to remind people you're not advertising. They're pretty nice batteries anyway.
You could make the the wires into a sort of "y" formation and then connect them to the battery.
Yes, it would be okay.
Thanks. I know they are...some people just don't think so though...
