There is a straightforward method to levitate magnets – and physicists are starting to grasp the way it works. The method may have purposes for robotics in the future.
In 2021, Hamdi Ucar – then at Göksal Aeronautics in Turkey – posted a YouTube video exhibiting two magnetic spheres levitating on both facet 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 consideration of Rasmus Bjørk at the Technical University of Denmark.
With a colleague, Bjørk determined to duplicate Ucar’s levitation method. “We sat down …
