Popis: This paper presents an investigation on the configuration of the particles of a magnetic fluid and its magnetization characteristic based on Monte Carlo method. The interparticle interactions caused by the magnetostatic energy, the repulsion energy, the van der Waals energy and the external magnetic field energy are calculated. In the calculation, the distribution of magnetic particles is assumed to be a lognormal distribution estimated from that of a magnetic fluid under the investigation. The calculation results for a magnetization characteristic and for the orientation of magnetic particles of a magnetic fluid are compared with magnetization curves constructed from measured values and with an electron micrograph of magnetic particles, respectively.
