Amazing Electricity!

Posted February 26th, 2010 by bigglesbarker and filed in lowerelectricbill

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.

    Nice little demonstration. Good work. Michael.

    Most DC motors need to use brushes to reverse the polarity on the windings at the right time to keep it spinning. Do you have any idea why yours doesn’t just line up the fields and stop there?

    I wonder if it would run better if you took the insulation off of only one side of the wire.

    what up wit da music

    i wonder if there is a way to make it use alot less enrgy like barely any, considering it oly uses a little any way…

    maybe a shorter or longer coil would cause it to draw less energy

    that was cool :)

    why dont you try it out and let us all know

    @ StormyKnight4life:

    Just a normal Baby 1,5Volt?

    that awesome!!! i wanna do that!!! do i just need a D battery Some copper wire two safety pens and a nickle?

  9. maxbrad60 says:

    I think it is bouncing on the safety pin due to the unbalanced / off centered nature of the copper wires. Take a close look at the right side copper wire in the video. This affect can also be achieved by sanding only half the insulationon the end of the copper wire.

    Never mind.. wow i feel stupid it says so in the beg of video.. i guess i just didn’t see it last time..

    MEN YOU ARE TRYING TO KILL ME!!!!!!!!!! I am trying to do these and i am stuck in the part of putting the tape and the pins, but whnt I am trying to put the big copper thing the positive and negative things of the battery are smoking hot! SO I HAVE BURNED MY SELF A LOT OF TIMES TRYING TO DO THESE! PLEASE EXPLAIN!

  12. 0o0oyeah says:

    dude…its not a nickle……its called a magnet lol

  13. JW93HB07 says:

    oh i do love magnets :D
    my girlfriend thinks that’s sad¬¬
    she doesn’t understand :P

  14. TiEEviL says:

    great

  15. lXsakuraXkissXl says:

    magnets.. ^_^ heavenly :)

  16. phoeniximperator says:

    pretty good!

    I usually use my lighter for deisolation … just burn a little and wipe with the edge of may fingers.
    PS:To all noobs , voltage doesn’t matter it can be raised or lowered through the inductance principles .. u need 2 solenoids and a pin

    USELESS, doesnt even cut your electric bill….

  19. Glowworm132 says:

    what gauge did you use for this???

  20. ramiskuey says:

    May be because you are striping the whole surface of the ends of the wire, and you are making just a short-circuit and it is just lost power and wire. So to avoid this loss you should only strip the side of the wire that is above in the terminals of the coil when it is verticaly seen. May be is the only one failure i see, can be done following this explanation. greetings everybody ;)

    I just wanted to answer to the issue of “julixjt”

  22. LelouchVBCGZERO says:

    niice trick, but i was hoping more like lightning bolts.

  23. mouser58907 says:

    Yeah you should only strip half the wire, that way for half a cycle the magnetic field is pushing the motor and the other half momentum carries it. Right now the 2nd half is slowing it down. We built one of these in my physics class and we got it to go extremely fast.

  24. ramiskuey says:

    Greetings, mouser58907 Where are you from? I got amazed that in your lectures of physics they are teaching that practical way. It is a way to show in an easy way how nature works and how you can use this nature work. Only the fewest teachers in the country i live are doing so. Are you the pupil or teacher? Anyway I think you are lucky to have such system of education. Many greetings ;)
