id="p0005">We discuss the importance of the dipolar interaction in magnetic nanoparticle samples.
id="p0010">It is shown that AC susceptibility may be used to estimate the extent of this interaction.
id="p0015">We develop a model that accounts for particle aggregation.
id="p0020">The theoretical model is then fitted to distinct magnetite samples.
