This study develops analytical relationships and computations of power dissipation in magnetic fluid (ferrofluid) subjected to alternating magnetic field. The dissipation results from the orientational relaxation of particles having thermal fluctuations in a viscous medium. r 2002 Elsevier Science B.V. All rights reserved.

Porous materials manufactured by freeze-casting are demonstrating potential application as oxygen carriers for the production and purification of hydrogen, or anode material lithium-ion batteries. However, to obtain required pore morphology sufficient mechanical strength, suspension processing parameters must be controlled. Fe2O3 nanoparticles/camphene suspensions were fabricated using stearic ...

This paper presents a wireless pressure sensor design based on magnetic fluid displacement over a planar coil and its corresponding inductance change. The design of the pressure sensor is presented followed by its fabrication and characterization. Experimental results show a good correlation with a nonlinear model relating the applied pressure to the change in coil self-resonant frequency. A pr...
