Anybody got any tips on how to model ferrofluids in FEMM?
In particular, how do I set saturation magnetization level?
Also, I am having trouble find any info on typical coercivity and permeabilities for ferrofluids.
I am currently using 2.7 for relative permeability, does this sound remotely...
Thanks for the help!
What if I don't have enough amp-turns to saturate even the iron core? (Currently using about 900 Amp-turns as I am very space and power limited)
In that case is there any advantage to using a more exotic core?
Also, can anybody reccommend a good reference book for...
Is there any real advantage to using very high permeability materials as the core of a cylindrical shaped electromagnet versus an iron core?
In particular, I am interested in generating an attraction (or repulsion) force between a permanent magnet and an electromagnet separated by about 1/4...
