We now know how rotating one magnet can make another levitate, a phenomenon that was initially completely baffling. 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. | New Scientist
