Spinning a magnet can make another one levitate – and now we know why

Researchers have filled in details of how rotating one magnet can make another levitate, a phenomenon they initially found completely baffling. Quickly spinning a magnet makes another levitate above it in a configuration much more unexpected than two magnets attracting or repelling each other. Frederik Durhuus who worked on the project says that you can make a magnet move away from another by aligning their like poles, but usually after a short time magnetic torque flips one of them and they end up sticking together. Here, rotation counters that magnetic torque, like how for a spinning top rotation counters the downward pull of gravity, he says.
