In the blood there are charged RBC, WBC, PLT, inorganic ions, so that there must be sensitive and complicated responsed of hemorheological properties under applied magnetic field. An experiment of constant magnetic field on apparent hemorheological viscosity was carried out. When the magnetic intensity was at 0.7T ,below the constant magnetic field, there is a decrease in apparent blood viscosy- ty, esp. the marked decrease in the whole blood and reductive viscosity under low shear[1]. Based on the above-mentioned experiment, another experiment was done. Indexed of hemorheological proper- ty under strong pulse magnetic field at an intensity of 1 - 2T are checked and compared with that un- der no magnetic field. The result showed a decrease in apparent blood viscosity under different shears of intensive pulse magnetic field, but the responsive sensibility of different individuals is different and also the best magnetic induction intensity affecting hemorheological property is different. It is closely related to the original sample blood of henorheological property. It suggests, when the pulse magnetic intensity is at 1 - 2T, hemorheological property may be improved and attention must be paid to the specificity of sensibility and responsive intensity of the individuals. When the pulse magnetic field is employed clinically, attention should be paid to the original different hemprheological property and to see whether the intensity is suitable and try to select the best one for the individuals respectively.
