Story summary

Researchers at Okinawa Institute of Science and Technology (OIST) developed a magnetic levitation system that eliminates eddy-current damping.
The design uses a graphite rotor disk paired with rare-earth magnets and axial symmetry.
The rotor spins with minimal energy loss and enables gravimetry and quantum experiments.
The study was published in Communications Physics and operates at room temperature.
The work points toward next-generation sensors and instruments for probing fundamental physics.
