The object of this study is ferrofluid. In the study the effect of polydispersity on the thermodynamic and magnetic properties of ferrofluids was investigated. In the first chapter of this paper we construct theory describing the thermodynamic properties of the bidisperse system of dipolar hard spheres. Computer program was developed that allows numerically to identify the thermodynamic characteristics of bidisperse ferrofluid. A comparison between theory and computer simulation was performed. In the second chapter the polydisperse model of dipolar hard spheres was considered. Additional new term in the existing approximation of the initial magnetic susceptibility of polydisperse ferrofluid was calculated. A comparison between theory and computer simulations was performed. The conditions for the availability of the new approach were defined.
