Free surface phenomena of magnetic fluid are considered to result from the competition among the interface stresses varying with the interface profile. Especially, the stationary interface profile is determined from the condition of flat distribution for the sum of stresses on the interface. Elucidation of free surface phenomena of magnetic fluid requires rigorous interface magnetic fields and magnetic stress differences under any interface profiles and applied magnetic field distributions. The interface coordinate vector in the Real Space as the function of the coordinate in the Flat Space is expanded into a series of periodic functions, and a set of expansion coefficients are used for characterizing the interface profile. On the basis of the interface magnetic fluid analysis previously developed, the dependence of the magnetic stress difference on these set of parameters is discussed together with the interface tension.
