Dangerous High-speed Magnetic Levitation

Back


See 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 "magnetman," also from wondermagnet.com. The pipes are thick-wall schedule-80 copper pipes from the scrap bin at Alaskan Copper and Brass. The motor is a replacement sewing machine motor from Grainger catalog. Speed control is a 1000-watt triac lamp dimmer.
