This is a unique variation of the worlds simplest motor, the homopolar motor. The difference here is that both the AA battery and neodymium magnet are the rotating motor parts. The battery and magnet hang from the steel welding rod wire holder, and a copper wire controls the power.

For Homopolar Motor Kits, with 3 magnets and 6 feet of copper wire, order from the good folks at the American Stirling Engine website: http://www.stirlingengine.com/ecommerce/product.tcl?usca_p=t&product_id=93

I order neodymium super-magnets from :

  • How much torque does this produce? Thinking of making a high amperage thermo-coupler to replace the battery and connect the neo. mag. to the copper + junction?

  • @joepipe101

    Haha, I was just looking at your video of the joepipe, before seeing your comment and was thinking the same thing!

    Your drawing is like a homopolar motor. The pipe is the battery. The electric and magnetic fields are there. The plasma is like the copper conductor connecting the battery plus and minus. (The plasma, or else the tube, should rotate in that case.)

  • @MrfixitRick

    Does this go forever? And where do u get neodymium magnets? Could you explain the different kinds there are? Thanks for this vid! I'm interested in learning more about this stuff!

  • @MadeInOregon27

    No, this motor will not run more than a few minutes, or up to perhaps a half-hour if one is lucky. I use NiMH rechargeable batteries.

    A good site to get and learn about magnets is K&J Magnetics. The link is in the "Show more..." box. You can also get a decent neo magnet from a shake-type recharging flashlight.

    Neo magnets come in various sizes and strengths. A N38 strength neodymium magnet is weaker than a N52, which is about the strongest. Check above site for details.

  • @joepipe101

    The torque in my device is perhaps an inch-oz or so. The torque is directly related to the strength of the magnetic field, and the current in the conductor.

    Note that for the homopolar motor, the magnet does not have to be directly attached to the battery, nor does the magnet have to rotate. It's the magnetic field strength that is important.

    Note too, if you generate resonating magnetic fields with the joepipe, then you can use coils of copper wire to collect power from it.

  • Fuckin magnets. How do they work?

    Hehe, I was naive and used to be offended by that statement....Insane Clown Posse, Miracles (2009)
