Magnetic fluids are colloidal suspension of surfactant-coated magnetic materials in a liquid medium where the sizes of the particles are of several nanometers.
Typically known as an example of functional fluid in the magnetic field, magnetic fluids, to simply put, are liquids that have magnetic properties. Magnetic fluids are attracted to the magnet and flow toward a magnet when brought near. In other words, the magnetic fluid can provide the restoring forces in the form of magnetic attraction. The strength of the magnetic field and the magnetization of the fluid affect the magnetization of the fluid affect the magnetic forces that hold the fluid in place. This means that the retention forces of the fluid can be adjusted by controlling the saturation magnetization of the fluid and the strength of the external field. |
