According to my online research, this experiment has not been done before on ISS.
FerroFluids - Ferrofluids are colloidal liquids made of nanoscale ferromagnetic, or ferrimagnetic, particles suspended in a carrier fluid (usually an organic solvent or water). It becomes strongly magnetized in the presence of a magnetic field.
In microgravity... natural convection, bouancy forces, sedimentation are absent. To be precise, even basic principles such as 'fluid flow' are greatly altered in Microgravity. So, due to applied magnetic field "Thermomagnetic convection" is also altered to a small extent in microgravity.
Hence, Thermal conductivity (Rate of heat flow) in a FerroFluid... will be different in microgravity.
Applications-
Study of this experiment has applications in developing advanced cooling systems, heat transfer systems, Ferrofluid deformable mirrors and other lot of applications in Aerospace industry.

NOTE :- The magnetic field used for the experiment is of small magnitude... hence it doesn't interfere with operation of other instruments onboard the ISS.
By plotting the graph of Temperature versus Time for the obtained experimental data thermal conductivity of ferrofluids can be calculated. The data can be fed to the computer onboard the ISS which can calculate the thermal conductivity.
