By means of image Helmholtz equation, linearity and non-linearity are identified from a visualized animation representing a physical dynamic system. The image Helmholtz equation method is a digital image processing methodology which is capable of extracting the characteristic values equivalently representing the modes of physical dynamic system. In this paper, a set of sequentially distinct magnetized SEM domain images is analyzed to extract behavior of magnetic domain dynamics. As a result, linearity is extracted in the Rayleigh magnetization region and non-linearity is extracted not only irreversible but also rotating magnetization regions.
