Magnetic levitation has not quite revolutionized the world of transit the way some of us might have hoped. It has, however, proven useful to [mrdiytechmagic], who has put the technology to grand ...
For instance, in maglev trains, powerful superconducting magnets create a strong magnetic field with diamagnetic materials to achieve levitation, seemingly defying gravity.
Magnetic levitation is a beautiful thing to watch. Seeing small objects wobble about while seemingly hovering in thin air never gets old. If you want something suitably distracting in this vein ...
