Correlation of rheological properties of ferrofluid-based magnetorheological fluids using the concentration-magnetization superposition
In this work, the yield stress previously measured for some ferrofluid-based magnetorheological fluids (FF-MRFs) with various volume fractions of nanosize magnetite ( φ) and micrometer size iron particle ( Φ F e), for a wide range of magnetic fields (B), is further investigated from a new point of v...
