通过自制的实验装置，对制备的两种不同的铁钴镍磁流变液进行了实验研究，分析了其在不同磁场强度下的导电、导热规律，并与铁钴镍磁粉本身的导电性和导热性进行了对比。结果表明：在磁场作用下，铁钴镍磁流变液和铁钴镍磁粉的导电性和导热性均发生明显的变化；在磁场强度在0~0.92T内增大时，铁钴镍磁粉的电阻会有两到三个数量级的下降，其导热系数从4W/(m•K)增加到13.2W/(m•K)，导热性显著提高，两种磁流变液的导热系数也均有提高。

An experiment on two prepared Fe-Co-Ni MRFs (Magneto Rheological Fluids) was conducted through a homemade device. Then, the electrical and thermal conductivities of the two MRFs wereare analyzed and compared with those of the Fe-Co-Ni magnetic powder itself. The results show that the magnetic field causes the electrical and thermal conductivities of the Fe-Co-Ni MRFs and magnetic powder to change greatly, and that, when the magnetic field intensity increases within 0~0.92T, the resistance of the Fe-Co-Ni magnetic powder decreases by two-to-three orders of magnitude with a significant increase in thermal conductivity increase which is from 4W/(m2•K) to 13.2W/(m2•K), and the thermal conductivities of the two MRFs also increase.
