Researchers devise several ways to orient nonmagnetic objects in 3D space using magnetic levitation

(Phys.org) —A team of researchers at Harvard University has come up with a way to move objects in three-dimensional space without touching them. As they describe in their paper published in Proceedings of the National Academy of Sciences, the technique involves suspending an object in a paramagnetic (very weakly attracted) liquid and then using magnets to manipulate the liquid to hold the object in place—levitating it.
