Ferrofluid

Oprettet lørdag 29 februar 2020

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.[1] The name ferrofluid was introduced, the process improved, more highly magnetic liquids synthesized, additional carrier liquids discovered, and the physical chemistry elucidated by R. E. Rosensweig and colleagues; in addition Rosensweig evolved a new branch of fluid mechanics termed ferrohydrodynamics.
