| Popis: | International audience; 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. |
