This Blows
.. my mind! lol.
right hand rule: say the electrons are going up to + terminal. stick yo right thumb up. your fingers are pointing in the direction of the newly created spinning magnetic field. if u could point your right thumb up 4 the other wire, and see the magnetic fields like wheels, both rotating ccw, put a wheel in the middle, it will go clockwise. the magnet is so strong that it makes the battery a big str8 magnet, but where those fields interact is where i get lost, because up and down are n and s, rgw wire mag field is like a wheel one side n one side s, spinning 90degrees to the updown n s battery, and the magnetic fields r acting like invisible gears turning. the 5 speed rig is just mindblowing. anyway that 90degree magnetic field interaction cuts down on magnetic drag/ lockup/pull/ friction.. but i believe also reduces the ability to do real, useful, harnessable w0rk. if you had 2 or more normal 2polar mags spinning where N attracts S attracts N, you could transfer mechanical energy, without the problem of worn out gear teeth, since the gear teeth are magnetic instead of material. but try putting those magnets like spinning [N-s] o [s-N] spinning, where o is a coil. monitor the electrical signals coming from the coil. i’d like to know what happen. or where o is an up-down magnet like the battery magnet combo. im pretty sure it would resonate trying to seek equilibrium. . as long as the[ns] [sn] magnets are spinning, you’ve built a 3 magnet vibrator! but it can be much more useful than a vibrator, if you put your mind to it.

why does the homopolar wire spin?

@v.dog: Amen! Firefox/Adblock Plus have made the net a nice place to visit.

Also, as a cave dweller I had never seen such a motor before and I think this post is great. Can’t wait to impress the nephews with it!

if you want to build the last one, have a look at http://fly.hiwaay.net/~palmer/motor.html
the trick is in step 2: leave some insulation (that is the clear coating) on one of the wire-ends, so that the coil shuts off for half a turn.

I just got my mind blown because I’ve spent my entire life knowing that magnets don’t stick to pennies (I remember from experimenting with magnetism as a kid)

Turns out our (Canadian) pennies have been able to stick to magnets since 2007…

you just found this ? So tell me why did you chose to live in the cave most of you life, since you escape from basement you was locked in by child molester for 10 years ?

Dear god why do people put these things on sites jammed with advertising, pop-ups and useless junk?!

And rebuttal. Didn’t realize which motor we where talking about… That’s what I get for shooting the yapper on the internet, I guess.

@Fallen:
That still wouldn’t make it commutated.

Great stuff, especially liked the 5 gear version on youtube. Crazy ferromagnetic space-bucks.

You can never get enough motor and engine design stuff.

I’d like to see this type in a more powerful design where it produces energy for a bigger system efficiently.

@jeditalian: if you magnet doesn’t conduct electricity, just put a washer or coin on top of it and touch the wire to that. It is not critical that the current goes through the magnet, it just has to be flowing.

looks like the magnet has to conduct electricity, so i might try wrapping a round black magnet with aluminum foil or something when i find one. sure it wont be as fast cuz it wont be neo, but this is cool nontheless

its NdFeB, some peope call em NIB for neodymium iron boron. i wish i had one lying around that had the poles arranged correctly. i dont wana break my hard drive magnets in half, and the other ones i have are way too small.
