A MAGNETO SENSITIVE FLUID COMPOSITION AND A PROCESS FOR PREPARATION THEREOF |
| 摘要 |
<p>The present invention relates to a magneto sensitive fluid composition and a process for preparation thereof, wherein the electrical conductivity of the composition varies drastically and reversibly in the presence of an external magnetic field. The composition, which is practically an insulator, starts behaving as a conductor in the presence of a magnetic field. The fluid is basically a magnetorheological composition in which the magnetic sensitive particles are doped with conductive dopants in the form of conductive metallic or non-metallic powder. The change in electrical conductivity of the composition is in addition to the change in rheological characteristics of the composition in the presence of an external magnetic field.</p> |
