在非均匀磁场中观察到过渡金属离子的运动。将含有Cr 3+、Mn 2+、CO 2+、Ni 2+和Cu 2+离子的溶液点样在硅胶载体上，并暴露于410 kOe（2）cm（-1）强度x梯度的磁场中。测量了金属离子的分布，并分析了运动的摩擦系数与金属离子的磁化率和浓度以及硅胶颗粒的尺寸的关系。当浓度较高时，金属离子向最大场移动得更远。结果表明，大量的金属离子和水分子在磁场中运动。
The movement of transition-metal ions was observed in an inhomogeneous magnetic field. The solution containing Cr3+, Mn2+, CO2+, Ni2+, and Cu2+ ions was spotted on a silica gel support and exposed to a magnetic field of 410 kOe(2) cm(-1) intensity x gradient. The distribution of the metal ions was measured, and the frictional coefficient of the movement was analyzed in relation to the susceptibility and concentration of the metal ions as well as to the size of the silica gel particles. When the concentration is higher, the metal ions move farther toward the maximum field. It is shown that a large group of metal ions and water molecules moves in a magnetic field.
