Building a simple electric motor with magnet wire, a D cell battery, two safety pins, some nail polish, and a rubber band.
<p>demais e muito facil de fazer</p><p><br></p>
i love your idea lol!
I kind of like it
not to rain on ur&nbsp;parade or anything, but adding nail polish may keep tha safety pins from connecting to tha wire. but its pretty cool anyway&nbsp;&nbsp; :)
Yes that is the point. You add nail polish to half the conductor so the circuit opens for every half rotation and the electric field collapses. That way the coil doesn't slow down from the magnet. It would slow down because as it rotates it's orientation changes and the opposing poles start distancing while the similar poles start approaching each other resulting in an opposing force.
It&rsquo;s very surprise! I bought a brand bag from brandbagfactory.com. It is very valuable. I often purchases products from brandbagfactory.com I think it&rsquo;s a good website. What you see is what you get!
The nail polish was a surprise for me. Great idea. <a href="http://www.adorababy.com/the-advantages-of-baby-shops/" rel="nofollow"><b>baby shops</b></a>
nice, i am searching this type of site.
Another (older) version that I've had on my web page for over 10 years: <br/><br/><a rel="nofollow" href="http://fly.hiwaay.net/~palmer/motor.html">http://fly.hiwaay.net/~palmer/motor.html</a><br/>
Is it possible to use alternating current to make it work? If not, how do you make the simplest AC motor? Regards.
where do I get the axle it could easily work?
so simple
Have you tried it because it doesn't work?
any idea on what kind of power it can make? I am trying to build a small car-like thing and wondering if this would work. obviously I would have to shrink the battery and the screw possibly, but I think it is possible. any clues?
oh the girl
i need to find one like that... a geek... who is good looking...lol...
yeh i know this thing very simple.who has posted this instructables is just a beginer i challenge!!
People, just read the PDF!
words were very hard 2 read then when u zoom in it gets all blurry
i had to change my id
i am going to enter this progect in a seience fair words to small i think too
This is a pretty elegant way to make a simple electric motor. I made an electric motor ages ago as a science project and I used a 9volt battery and had to improvise a brush system. Pretty overkill for something that just has to spin. The nail polish eliminates the brush issue which cuts the power in half, but it much simpler.
Just download the pdf file, you can zoom in
