There’s a easy approach to levitate magnets – and physicists are starting to know the way it works. The method might 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 revealed a paper on the phenomenon, which attracted the eye of Rasmus Bjørk on the Technical College of Denmark.
With a colleague, Bjørk determined to duplicate Ucar’s levitation method. “We sat down …
