ronthepon Posted August 23, 2006 Report Share Posted August 23, 2006 I am interested in making a ferromagnetic fluid. (i.e. a fluyid which strongly attracts magnets) Anyone got any ideas on how it could be done? Quote Link to comment Share on other sites More sharing options...
Mercedes Benzene Posted August 23, 2006 Report Share Posted August 23, 2006 Sodium silicate and Iron(II)(III) Oxide. That might work, but the particles of the Iron Oxide would need to be extremely small: probably 1000 mesh or more. I'm not sure, but this is my best guess. You could always buy some. ;) Quote Link to comment Share on other sites More sharing options...
cwes99_03 Posted August 23, 2006 Report Share Posted August 23, 2006 Ferromagnetic fluids have been actively studied all around the world. I remember seeing a demonstration in a small state college lab back in 1996. There should be a lot of web material on them. Quote Link to comment Share on other sites More sharing options...
