Derivation for Electric Current Regulation Equation of a Gradient Magnetic Field to Control Suspending Magnetic Particles Inside Dialysate Solution

To allow a better adsorption performance inside a novel magnetic adsorption device designed in the process of hemodialysis, the mechanical properties of magnetic absorbents trapped inside a two-phase system are studied in this paper. A gradient magnetic coil field was assumed to produce the magnetic driving force that balances other hydraulic forces for the adsorbents. Applying this field, a complement practical form of winding equation for the solenoid coil is obtained. The case studies are also made in this paper to explore the design of the field.Copyright © 2016 by ASME
