Magnetorheological Fluid

Magnetorheological Fluid Latest News

Recently, scientists at the Indian Institute of Technology (IIT) Patna have developed an innovative hybrid magneto-rheometer that promises to advance research and applications of magnetorheological (MR) fluids. 

About Magnetorheological Fluid

• It is a fluid that has good magnetic properties.
• MR fluid responds to the magnetic field and changes its properties when a magnetic field is presented.
• Property: These fluids can rapidly change their mechanical properties when exposed to a magnetic field, increasing in apparent viscosity, to the point of becoming a viscoelastic solid.  
• Composition: These fluids contain magnetic micro-sized iron particles, non-magnetic-based fluid, and some additives in order to mitigate sedimentation and agglomeration.
• Carrier fluids: The various carrier fluids used in the preparation of MR fluids are mineral oil, silicon oil, castor oil, soybean oil, kerosene, synthetic oils, honge oil, organic oil, water-based oils, etc.
  • However, for obtaining better vibration control, silicone oil is the most preferred one due to its higher viscosity index, lower friction characteristics, higher flash point, and higher shear strength. 
• The fluid can transmit force which can be controlled with an electromagnet, giving rise to its many possible control-based applications.
• Potential Applications: It is ideal for adaptive technologies such as brakes, clutches, shock absorbers, vibration control systems, dampers, actuators, and medical devices.
