The properties of a one-dimensional array of single-domain ferromagnetic particles are analyzed using the original simulation method. Despite the simplicity of the system, it is shown that its properties are quite diverse. Magnetic configuration and magnetization curves are studied in the whole range of fields of interaction including distances wherein the interaction could be still considered as a dipole-dipole. Along with a purely academic interest, the results may be of practical value in the field of creation of new instruments based on magneto-resistance effect. A comparison with experiments showed that the model adequately reflects the properties of real systems.
