  1. Symbol i stands for number of nanoparticles in the aggregate. Averaged F mg is the magnetic force between the nanoparticle and an aggregate with averaged vectors of polarizations and destinations of nanoparticles in the aggregate. Summed F mg is magnetic force between the nanoparticle and the aggregate computed by summation of magnetic forces between the nanoparticle and all the nanoparticles in the aggregate. Symbol Deviation stands for averaged value of absolute deviations of data points from their mean value. Distance between the nanoparticle and the aggregate is one thousand multiply of radius of the aggregate
