audioguru Posted July 28, 2004 Report Share Posted July 28, 2004 Mazzag,Yeah, sure.But if a big magnet above an iron globe pulls it up, what causes it to stop pulling so much when the globe is levitating?If you put a magnet above and another magnet below, then the globe will be attracted to the nearest one, and wouldn't stay in between.I don't see any optical sensing for electromagnet control.

MP Posted July 29, 2004 Report Share Posted July 29, 2004 If you put a magnet above and another magnet below, then the globe will be attracted to the nearest one, and wouldn't stay in between....I suspect it is the opposite principle. They are most likely repelling...MP Quote Link to comment Share on other sites More sharing options...
