There’s a easy technique to levitate magnets – and physicists are starting to know the way it works. The approach may have functions for robotics sooner or later.
In 2021, Hamdi Ucar – then at Göksal Aeronautics in Turkey – posted a YouTube video exhibiting two magnetic spheres levitating on both aspect of a quickly spinning bar magnet that was positioned with its north-south poles oriented vertically. Ucar additionally printed a paper on the phenomenon, which attracted the eye of Rasmus Bjørk on the Technical College of Denmark.
With a colleague, Bjørk determined to copy Ucar’s levitation approach. “We sat down …
