An experimental device for liquid magnetically sensitive materials

Abstract

The invention provides an experimental device of a liquid magnetic sensitive material. The experimental device includes a yoke, an armature, a heating plate, a sample cell and a magnetic field detector. The yoke has a U-shaped structure and the upper end of the U-shaped arm of the yoke is folded and bent vertically inward so as to form a magnetic gap. The sample cell is arranged in the magnetic gap, and two bent end faces of the U-shaped arm of the yoke are in contact with the cell wall of the sample cell. The heating plate is fixedly arranged at the bottom of the sample cell. The armature winds the middle section of the U-shaped yoke. The magnetic field detector is located above the sample cell and a detection probe is located in the liquid magnetically sensitive material contained in thesample cell. The experimental device is compact in structure, high in magnetic flux and low in generated working heat. At the same time of magnetic field generation, the temperature of the experimentmaterial can be controlled, the experiment material can be stirred and the value of the magnetic induction intensity can be measured, and change of characters of the experiment material under the single or combined action of the magnetic field, temperature and stirring can be observed, which make the research of the magnetic property of the liquid magnetic sensitive material convenient and quick.

Description

technical field [0001] The invention belongs to the technical field of magnetic field generators, and relates to an experimental device for liquid magnetically sensitive materials and a method for detecting the magnetic response of liquid magnetically sensitive materials. Background technique [0002] Magnetically sensitive materials are an emerging material research direction. Magnetically sensitive materials are widely used in chemical, medical, petroleum, environmental protection and other industries. [0003] But so far, there is a lack of special experimental equipment for the magnetic response characteristics of the core performance of magnetically sensitive materials. Some of them use permanent magnets to generate magnetic fields, which are unstable and uneven. Some use ordinary electromagnets to generate magnetic fields, which are huge in size and high in energy consumption.
