Graph of limit distances of two interacting aggregates. Crosses represent limit distances computed by averaging of magnetic forces. Squares stand for sum of magnetic forces of every nanoparticle from one aggregate and every nanoparticle in second aggregate. On the left side of the graph, gravitation force effects on the smaller aggregate, on the right side, gravitation force effects on the bigger aggregate.
