Consider a solution that one of it's components is sensitive to magnetic field. Is it possible to separate it by magnetic force? Or not? Is magnetic force strong enough to weaken the interactions between the components of the solution?
I have one that is similar to the topic which you have asked
Silicon oil and iron particles of nano size is mixed and placed in a magnetic field the mixture turns into a solid material and when the magnetic field is removed the solid material turns into liquid state.
magnetic field can separate all ferro and para materials (or particles) together within solution, this is of course need to be repeated several times to get better purity.
