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

Researchers at OIST built a graphite disk that levitates and spins for hours in a vacuum, showing how perfect magnetic symmetry can cancel energy loss.

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 ...
