Experimental Study on Flux Control Characteristic of Magnetic Fluid controlled by Parallel or Orthogonal Magnetic Field

Abstract

This paper shows the experimental results of the flux control characteristic and inductance controm characteristic of magnetic fluid which is controlled by the permanent magnets. Two kinds of magnetic field, parallel and orthogonal, are comparatively discussed. The position between the magnetic fluid and the permanent magnet determines the magnetic field. The results are useful in using magnetic fluid as a sensor or a control element.
