From the formulate for different two dimensiona l magnetic anomalies the indefinite integral transformations for various anomalies are derived and figures for different parameters are presented. In this paper, two kinds of magnetisms abnormality with normal formation are chosen and the various regulations or characteristics of figures under different sites and dime nsion parameters of statute appearance magnetisms are discussed. A series of reg ulations toward various object modes is concluded. Finally, the advantages of th e methods through comparing to the figure before transforming are analyzed. This kind of device will discover a few of important information and benefit to the explanation of magnetic abnormality.
