Vertical flotation of particles in a paramagnetic fluid

The mineral particles with different densities and magnetic volume susceptibilities were levitated at different heights similar to the results obtained previously by others. It proves that the magneto-Archimedes relevant equation can be used for later check and design purpose for the object levitation in the magneto-Archimedes agent solution. The cryogenic liquid which is similar with the composition of liquid air can effectively separate most kinds of pure mineral particles. The experiment results show that liquid air provides a potential possibility to act as the magneto-Archimedes agent in future.
