Smart magnets are here, and their potential could be huge. The company Correlated Magnetics uses advanced printing technology to create what they call Polymagnets, which have custom magnetic fields. The magnets can have multiple north and south poles on a single side, enabling engineers to develop faces that repel each other only until they are twisted into a certain position, at which point they lock together.
The team can also adjust the pull strength of each magnet, and print magnetic field designs on flexible materials as well as traditional, rigid ones. The applications of this technology haven't been fully explored yet, but so far the magnets have been used as frictionless gears that both attract and repel each other to stay together without touching.
We've collected some great videos on the future possibilities of printable magnets. Watch them below. And find out more about how magnets are shaping the future, from space travel to magnetic levitation to the future of phone technology.
