| Popis: | A magnetic fluid is a kind of multiphase fluid which consists of a stable colloidal dispersion of magnetic particles in a liquid carrier. The most basic factor governing its behavior is magnetic susceptibility. We describe the research on a measurement apparatus for magnetic susceptibility of a magnetic fluid by means of electromagnetic measurement. The apparatus is equipped with an electromagnet having a very low residual magnetization and magnetic field gradient adequate to secure a measurement of high accuracy. The measurement results of magnetic susceptibility with this apparatus are also reported for several kinds of magnetic fluids in various magnetic fields, temperatures and concentrations. |
