Iranian Researchers Produce Toys, Entertainment Equipment by Using Magnetic Nanofluids
“One of the plans of the research group is production of materials based on magnetorheological fluid or MRF which is a fluid that takes special arrangements in the presence of magnetic fields and can have different applications,” said Masoud Azimian, one of the researchers.
He explained that an application of these materials is polishing the surface of military lenses, adding that now these fluids are used in production of toys and entertainment kits.
“We produced slime paste from MRF fluids in the presence of magnetic fields. This paste will take different shapes inside the MRF fluid and under the magnetic field,” Azimian said, noting that these fluids are manufactured based on iron nanoparticles.
Magnetorheological (MR) fluids are a class of smart materials whose yield stress increases considerably in the presence of externally applied magnetic field.
These fluids are composed of soft, spherical, magnetic particles whose diameters range from 0.01 to 20 µm dispersed in an organic liquid. Magnetorheological effect and sedimentation stability are two important factors that make a good MR fluid.
Experimental studies mostly concentrate on the synthesis of MR fluids with high yield stress and enhanced sedimentation stability.
