摘要:
本文研究了一种新型的软磁复合系统。铁磁流体乳液研究表明,这是通常已知的乳液的非典型的强磁性能。研究了磁流体乳状液与磁场的相互作用。在这些介质中的结构转换,如变形的乳液微滴和乳液反转,进行了研究。研究了与结构转变有关的乳状液相对渗透率的变化。发展了所观察到的现象的理论,并证明了通过施加磁场来有效控制铁磁流体乳液的磁性能的可行性。
英文摘要:
In the paper the novel soft magnetic composite system is investigated. A ferrofluid emulsion studied demonstrates the strong magnetic properties which are atypical for commonly known emulsions. Interaction of ferrofluid emulsions with a magnetic field is considered. Structural transformations in these media, such as deformation of emulsion microdroplets and emulsion inversion, are studied. The changes in the relative permeability of emulsion associated with structural transformations are investigated. The theory of the observed phenomena is developed, and the feasibility of effectively controlling the magnetic properties of ferrofluid emulsions by applying a magnetic field is demonstrated.
