Magnetorheological Fluid - Customization of Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:
The material inside the organic glass cover of the exhibition items is magnetorheological fluid. Magnetorheological fluid is a controllable fluid composed of small soft magnetic particles with high magnetic permeability and low hysteresis, mixed with non-magnetic liquid. Under normal conditions, it is a suspension and exhibits low viscosity Newtonian fluid characteristics; Under the action of a strong magnetic field, suspended particles change from magnetic neutrality to strong magnetism due to magnetic induction, thus interacting with each other and forming a "chain" shaped bridge between the magnetic poles, which then transforms into a macroscopic columnar structure, causing them to instantly change from liquid to viscoplastic, and their rheological properties undergo a sharp change, exhibiting high viscosity and low fluidity Bingham fluid characteristics. When the applied electric field strength is significantly lower than a critical value, the magnetorheological fluid becomes liquid; When the electric field strength is significantly higher than this critical value, it becomes solid. Near the critical value, its viscosity increases with the increase of electric field strength, making it difficult to say whether it is in liquid or solid state. At present, both domestically and internationally are competing to develop this technology. With the deepening of research and the improvement of MRF performance, magnetorheological fluids are gradually being applied in industries such as grinding and polishing, home fitness equipment, printing, etc. The fastest research and development is in the application fields of automotive shock absorbers, brakes, etc.
