Dangerous High-speed Magnetic Levitation Maglev

Complete info at http://amasci.com/maglev/magroll.html

EM repulsion lifts a neodymium magnet above two spinning copper pipes. Also see http://www.youtube.com/watch?v=jOaBnJpIRzM I bought my supermagnets from Mr. George http://supermagnetman.net also from http://www.wondermagnet.com.

This demonstrates one type of Maglev train, the kind lifted by induced current repulsion in a conductive track. Only usually the track stays still and the magnets move fast. It's related to superconductor levitation, but done with high speed motion.

The pipes are several pounds each, thick-walled "schedule-80" copper from the scrap bin at Alaskan Copper and Brass in Seattle. Shaft pins were cryo-fit and turned on a lathe to mate with 1" ballbearing races. The motor is an AC/DC replacement 5000rpm sewing machine motor from WW Grainger catalog. Speed control is a 1000-watt triac lamp dimmer.

[fairyheli2]

where do you get these motors?

[wbeaty]

@fairyheli2 for full info, click on the link to project page, magroll html. It was Dayton motor from Grainger catalog, search on universal AC/DC motor, 1/15 horsepower 5000 rpm

...so many smart words o.o" I just watched to see something blow up

[wbeaty]

@littlemissluluable up to my shOULDERRRRAAAAAAAAAAAAARRRG!  spletch.

Also, I assume 23mph is the key not the RPM, so larger pipes would work at slower rpm. Can spinning magnets suspend copper?

[wbeaty]

@bastian74 Yep, in theory I think thicker pipes could spin slower for same lift.

Can't just be spinning magnets, copper must see AC fields. Cover a spinning cylinder with a checkerboard of NSNS pole array? Large pole diameters for high lift. Or a radial rosette of spinning wheels with NSNS magnets on the rims, place hollow copper sphere in the center.

@Meldola07  When 5mi high in altitude, you're in a radioactive environment, over 100x more intense than normal background radiation. Geiger counters chatter like crazy. Pilots get early-onset cataracts. Does cosmic radiation affect your brain? Experimenters report that x-rays to the skull make you sleepy, and cause a "lost time" effect.

So, does air travel seem to go by much more quickly than it should, while bus or train travel doesn't? That would be the radiation affecting your neurons.

u r a smart guy good for u...i need u to forget about solid magnets....i need u to spin ferro fluid at these high speeds..i wonder what will happen if u achieve the exact rpm...also incase your project in a vacum....u wont need as high of speed....to this day no one has explained why the mag field changes in vacum

[skippy4290]

this is not new science lol..was invented in 1983 ....its called a levitron look it up lol..o ya u have looked it up.......i myself made what u have 15 years ago...now theres easyer methods than this

[prajd60]

impressive!! whats the total cost of this project?

[bask185]

Now is this Electro Dynamic Suspension?

[Fourteen88SoCal]

...that was anti-climactic

cool device though!

[stinkkingstink1]

this has to be one of the safest things I have ever seen.

@Zod011 I just dislike your comment just for trolling u.

[Zod011]

Nobody likes me :'(

[taresFlyInCircles]

@Zezimacall fuckin' miracles

[Zezimacall]

how do magnets work.
