Development of the labyrinthine patterns arises in a wide variety of the systems. Here the labyrinthine pattern formation is studied in the disordered system of the magnetic fluid drops. By the numerical simulation it is illustrated that in the present case labyrinthine pattern formation occurs due to the fingering instability of the separate droplets and mutual repulsion of the arising stripes. The structure factor of the highly disordered system of the magnetic fluid stripes is calculated, and it is shown that the characteristic distance between stripes coincides fairly well with the period of the equilibrium system of the infinite straight magnetic fluid stripes.
