A Ferro fluid is a colloidal substance containing ferromagnetic particles that fall in size range of about 1nm to 100 nm, which obeys the official definition of a Ferro fluid adopted by the European commission. Hence a Ferro fluid may be classified as a nanomaterial. It consists of Nano ferromagnetic particles suspended in a carrier fluid with a surfactant such as oleic acid to prevent agglomeration of ferromagnetic particles. Ferro fluids have had revolutionary applications in many fields ranging from Speakers to Space. They are constantly finding new applications in various fields due to their intrinsic properties. The parameters such as 1) The carrier fluid 2) The magnetic field intensity 3) The surfactant, which can be modified to change the properties of a Ferro fluid. Considering their highly diverse applications, it is desirable to study the change in behaviour of a Ferro fluid upon modification of above said parameters. Hence my study involves the change in viscosity of a Ferro fluid upon application of magnetic field of different intensities. The Ferro fluid considered in the following study uses paraffin wax as a carrier fluid instead of more conventional carrier fluids such as kerosene.
