Abstract : A heat pipe or thermosiphon device is provided which may be configured for operation in various temperature regimes from cryogenic to elevated temperatures and in gravity or other orientation sensitive environments, as well as zero-gravity or other orientation insensitive environments. The invention comprises a heat pipe, containing a magnetically susceptible liquid as the working fluid, surrounded by an electro-magnet or permanent magnet which produces a magnetic field gradient which interacts with the magnetically susceptible liquid to produce an artificial body force field analogous to, but which may be substantially greater than, the gravitational force field, for separation of the liquid from gaseous phases of the magnetically susceptible working fluid within the heat pipe.
