The authors discuss some properties of the equation of state and of the static correlations for spherical ferromagnetic grains, at thermal equilibrium, in a passive fluid. At high external fields H, low concentrations, and not too high temperatures, the grains tend to form chains along the directions of H. In zero field but otherwise identical conditions, some chains are still present but oriented at random and in competition with closed rings and clusters. Various experimental methods which could give information on these chain structures are listed. Author
