RÉSUMÉ

Numerical computations were carried out to study convectional mode and electrical field in silicon melts in a cylindrical container which is sufficiently long in an axial direction under no magnetic field and a rotating magnetic field for various rotational rates of a cylindrical container and a magnetic field. Under no magnetic field, fluid represented a rigid rotation for Pr=0.013 and Recyl=1 183. Under a rotating magnetic field, Lorentz force in a circumferential direction was found to work when the rotational rate of a magnetic field and that of a cylindrical container were different. Computations were carried out for the combination of parameters such as Pr=0.013, Recyl=0, 1183, Remag=1183, 2366, -1183 and Ha=21.5, 53.7. For these cases, except near the container wall, fluid in a cylindrical container rotated with the rotational rate of a magnetic field.
