Complete info at http://amasci.com/maglev/magro... repulsion lifts a neodymium magnet above two spinning copper pipes. Also see http://www.youtube.com/watch?v... 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..Lots more stuff at SCIENCE HOBBYIST http://amasci.com/unew.html.No... trolls/spammers blocked immediately, zero tolerance

how the ball flot because of spin.?im just 14 years old so i didnt know lots.,!!

@TheGimpMaster01 97Hz gives about 23MPH surface speed. Imagine a car going 23MPH, but with tiny wheels like a skateboard. (If it was 97KHz or 97MHz, the car would be going 23,000MPH or 23e+6MPH, either of which would vaporize it like a meteor.)

just wondering... on your oscilloscope, did it say 97.3 Hz or 97.3MHz? because that ought to change the surface velocity of the copper pipes quite a bit. I actually found this very interesting having just taken a university classical physics course in which we talked about magnetic induction and electric fields.

i wanted to see something going between those tubes =D

@wbeaty copper or aluminum.... or something that wont corrode under the high heat.... stainless?

@hvguy your brain is irradiated by 50x background radiation during plane flights (sometimes more.) Nikola Tesla used this technique to get ideas. And... spinning pipes must be copper or aluminum, not steel or brass.

airplane flight.... AKA drug trip... its a sewing machine motor spinning 2 copy machine tonor reels...

6000 rpm he said 24 mph

how many rpms is that thing????

Very nice demo wbeaty!!I personaly think that magnetism hold the key to cracking the holy grail ? whats that you say?Tavelling at the speed of light..As there is no friction with anything
