| Abstract: | In this paper, a research on susceptibility anisotropy of artificial samples of magnetic sandstone, on which three kinds of strain are exerted in a weak magnetic field, is reported. The results indicate that an obvious correlation appears between the susceptibility ellipsoid and the strain ellipsoids. And an analysis of the mechanism of the features of susceptibility aniso-t'ropy and remanent magnetism of these samples are given under the condition as mentioned above. |

| Keywords: | Susceptibility anisotropy Artificial sample Susceptibility ellipsoid Strain ellipsoid |
