With a clever design, researchers have solved eddy-current damping in macroscopic levitating systems, paving the way for a ...

STORY: A UK startup is using soundwaves to make objects levitate in midair. And London-based AcoustoFab says it's "acoustic levitation" is not just a neat trick. It could also have commercial ...

The new levitating rotor works because of its rotational symmetry. Unlike plates that move up and down in varying magnetic fields, the spinning rotor stays within a constant magnetic flux. This ...
