In homogeneous magnetic fields, the sensor exhibits a sensitivity of 307.453 mV/Oe. The minimum measurable signal (i.e. noise level) of this experimental setup was found as small as 0.782 mV, which reveals a possible detection limit of 3{$\times$}10?8 emu . Our report presents the simulation and the measurement of magnetic fluids of various magnetic Fe3O4 nanoparticle concentrations. The results open a possibility of using this sensor for medical and bioengineering applications.} }
