Macro-clusters formation of the magnetic colloidal particles in magnetic fluids is in-vestigated. Experiments of an optical microscope observation of the macro-clustersformation and of anomalous light scattering by the magnetic fluid are reported. Look-ing upon the anomalous light scattering of the magnetic fluid as a kind of criticalopalescence and using Debye's opalescence theory, we derive a thermodynamicalinstability theory of the colloidal particles' dispersion. Relations among the instability theory of Cebers, that of Sano and Doi, and ours are discussed. An interactionenergy among the colloidal particles is evaluated from the light scattering experiment.Similarities among the macro-cluster formation, spinodal decomposition of precipita-Lion-type magnetic alloys, and flux-line lattice formation in type-II superconductorsare discussed.[magnetic fluid, macro-cluster, agglomeration, critical opalescence, colloidal ll instability, light scattering, spinodal decomposition, negative surface energy l
