| Abstract: | Blood is a characteristic biological fluid which behaves as a magnetic fluid due to the complex interaction of the intercellular protein, cell membrane and the hemoglobin, and exhibits considerably high static electric conductivity which is hematoerit and temperature dependent. Its electric and magnetic properties are the key factors for controlling blood flow in electromagnetic fields. This paper introduces the electric model of whole blood impedance, formula for whole blood＇ s electric conductivity, impedance and magnetic susceptibility, and the mechanism of action of electromagnetic fields on blood. It conduces to the accurate mathematic model of blood flow in electromagnetic fields. |
