磁流体(Magnetic Fluid)是将胶体微粒级的强磁性物质粉末分散在波相中的胶体溶液.该胶体溶液的分散稳定性极佳,在普通的离心力或磁场的作用下,无沉降和凝聚现象,磁流体在外观上具有流体的性质.1965年美国帕皮尔(Papell)提出将喷气核燃料磁流体化,在失重的条件下通过磁性定位的方案后才开始被重视,并在与美国航空、航天管理局(NASA)计划有关的各个方面进行应用研究.其后,随着宇宙计划的缩减,该研究自然就转向民用方面了,但目前对这种前所未有的磁流体特性,尚未充分
Magnetic Fluid is a colloidal solution in which a colloidal particle-sized ferromagnetic material powder is dispersed in a wave phase, and the colloidal solution is excellent in dispersion stability and shows no sedimentation and aggregation under ordinary centrifugal force or magnetic field , The magnetic fluid has the appearance of the fluid nature of the United States in 1965 Papel (JetPierll) proposed jet nuclear fuel magnetic fluidized, under the conditions of weight loss through magnetic positioning program began to be valued, and in the United States aviation, aerospace Applied research has been conducted on all aspects of the NASA program and subsequently moved to civilian aspects as the cosmic program shrinks, but to date this unprecedented magnetic fluid character has not yet been fully developed
