Abstract
Natural convection using a magnetic fluid was studied in a square cavity under the influence of a permanent magnet. The aim
was to explore the degree by which heat transfer may be controlled, enhanced or reduced, by investigating a set of different
distances of a permanent magnet to the cavity. These distances of the magnet were set such that the cavity was in some cases
fully dominated by buoyancy or by the magnetic body force and in other cases partly dominated by either of both body forces
in different parts of the fluid. The effect on heat transfer was characterised by an averaged Nusselt number, Rayleigh and
magnetic Rayleigh number.
