本文研究了在温度梯度作用下浸入液态金属中的固体导电粒子的热电效应。静磁场的叠加在固体和液体中均感应出热电磁（TEM）力。考虑一个简单的球形粒子，电流密度和相应的力可以解析计算。根据磁场相对于温度梯度的取向，考虑了两种情况。在这两种情况下，相应的颗粒周围的流场计算。谷物的运动进行了分析，在前面进行的原位实验的光。
The present paper deals with the thermoelectric effect on a solid electrically conducting particle immersed in a liquid metal under a temperature gradient. Superimposition of a static magnetic field induces thermoelectric magnetic (TEM) forces both in the solid and in the liquid. Considering a simple spherical particle, the electric current density and the corresponding forces can be calculated analytically. Two cases are considered according to the orientation of the magnetic field with respect to the temperature gradient. The corresponding flow fields around the particle are calculated in both cases. Grain motion is analyzed in the light of in-situ experiments performed earlier.
