Abstract

The coupling of an external magnetic field with the gradients of temperature and particle concentration in a magnetic fluid leads to a magnetic body force that tends to drive the fluid unstable. Our experiment shows that multiple instabilities can occur in the presence of an oblique magnetic field. The phase diagram for the critical field has been determined, which indicates that these instabilities are induced by the vertical component of the field. However, the multiple unstable states are primarily controlled by the horizontal component. The dynamics include traveling rolls, oscillating waves, and other temporal patterns. © 1999 Published by Elsevier Science B.V. All rights reserved.
