Figure 4.

Effective range of the magnetic forces of chosen aggregates. The dashed line characterizes the effective ranges for the interaction of aggregates interacting with a single nanoparticle. The solid line characterizes the effective ranges for the interaction of two aggregates of the same size. The graph is plotted for the magnetic polarization 170 emu g-1.
