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.
