研究了磁化率很小的水和硫酸铜水溶液在磁场作用下的表面形貌。当在水平超导磁体中施加10 T的场时，蒸馏水的表面在场中心处相对于零场区域处的水平降低39 mm（摩西效应）。与此相反，接近饱和的硫酸铜水溶液的表面在中心升高了大致相同的高度（反向摩西效应）。分别根据蒸馏水和硫酸铜水溶液的顺磁体积磁化率值和对磁体积磁化率值，对这些分布进行了系统的解释。
Magnetic field effects on the surface profile have been investigated for water and copper sulfate aqueous solutions that have very small magnetic susceptibility. When a field of 10 T is applied in a horizontal superconducting magnet, the surface of distilled water was lowered by 39 mm at the field center, relative to the level at the zero field region (Moses effect). In contrast, the surface of a nearly saturated copper sulfate aqueous solution was raised by roughly the same height at the center (reversed Moses effect). The profiles were systematically explained based on the dia- and paramagnetic volume susceptibility values of distilled water and copper sulfate aqueous solution, respectively.
