Sedimentation of nanopowders of magnetite in a water solution at presence and absence of a gradient magnetic field accelerating sedimentation is studied on special laboratory setup. It is shown that in water solution there is a formation of aggregates of the micron sizes from nanoparticles of magnetite. A major factor leading to aggregation of nanoparticles of magnetite in micron clusters is the magnetic attraction between particles.
