Abstract
Ferro fluids are colloidal suspension of magnetic particles which respond to external magnetic field enabling the possibility of charging the magnetic flux by moving an external magnet about it. In this present study iron powder are first synthesized with water and surfactant in the lab using co-precipitation technique followed by ferrofluid preparation, magnetic properties are characterized. Here ability to produce a fluid phase of magnetic material to demonstrate the generation of energy using a simple set up and this energy is demonstrated to produce useful work. Ferro fluids are successfully synthesize and experimental result shows generation of voltage change between 15-85 volts at critical parameter such as force measurement which has been made and illustrated analytically for different voltage. The counter load sustained ferrofluid of different percentage of ferrous powder and surfactant have been observed by increasing in applied voltage. It has been also observed that increase load is accomplished with increase in ferrous powder concentration.
