In summary, polarity-free magnetic repulsion is a phenomenon where two magnets with opposite poles facing each other are able to repel one another without the need for one magnet to have a specific polarity. This is due to the alignment of the magnetic fields of the two magnets, which causes them to push away from each other rather than attract. This concept is utilized in various technologies, such as magnetic levitation and magnetic bearings, and has the potential to revolutionize transportation and energy storage. Overall, polarity-free magnetic repulsion works by harnessing the natural properties of magnets and manipulating them to create a repulsive force.
