Thermal liquid propulsion system using magnetic nanofluid

Magnetocaloric materials: From micro- to nanoscale

“…157 The ferrofluid containing magnetic particles immersed in a liquid solution has been further developed for microfluidic pumps. 29,158,159 The concept also introduced by Rosensweig is as follows: since magnetic materials lose their magnetization as the temperature approaches the material T C , then by exposing a column of magnetic fluid to a uniform magnetic field coincident with a temperature gradient will produce a pressure gradient in the magnetic fluid. As the fluid heats up, it loses its attraction to the magnetic field and is then displaced by the cooler fluid.…”
