Does COMSOL materials library has a B-H curve for Ferrofluids or is it modelled as a linear paramagnetic material?

Hi Krishna, Comsol does not have B-H Curve defined for ferrofluids and neither it should be modelled as linear paramagnetic material (can be for weak magnetic fields). You need to provide B-H curve externally obtained through VSM/SQUID measurements of fluid samples or theoretical Langeving model.
