Ferrofluid Wikipedia

A ferrofluid or ferromagnetic fluid is a liquid that becomes strongly magnetized in the presence of a magnetic field.. A process for making a ferrofluid was invented in 1963 by NASA''s Steve Papell to create liquid rocket fuel that could be drawn toward a pump inlet in a weightless environment by applying a magnetic field. The name ferrofluid was introduced, the process improved, more highly
