Figure 7.

Graph of limit distances of interacting aggregate with one nanoparticle. Solid line represents attractive magnetic force between an aggregate and a nanoparticle on which gravitation force effects. The dashed lines represent attractive magnetic force between a nanoparticle attracting an aggregate. Square marks represent data computed by averaging, triangle marks stand for sum of magnetic forces of a nanoparticle and all nanoparticles in an aggregate.
