It is widely known that pulsed magnetic field (PMF) is very useful tool to manipulate chemical and physiological processes in human body. The purpose of our study is to observe dynamics of rouleaux patterns of red blood cells (RBC) under PMF. The aggregation of RBCs or rouleaux formation is caused by fibrinogen in blood plasma. The maximum magnetic field intensity is 0.27 T and pulse time of 0.102 msec and pulse repetition rate was 1 Hz. PMF stimulus was applied to the palm of left hand for 5, 10, 15 and 20 min. Live blood analysis was used in vitro in order to quantitatively estimate the velocity of RBC exposed to PMF stimulus. The velocity of stacked-RBC of 10 minute PMF stimulus was increased up to $8{\times}10^{-4}m/sec$, but it decreased rapidly as the time passed. The results of present study have adduced that PMF stimulus on hand provide the improvement of RBC rouleaux formation, increase of RBC's moving velocity as well as low blood viscosity.

The change of rouleau formation of red blood cells in the hand stimulated by pulse magnetic field having a maximum intensity of 0.27 Tesla and pulse duration of 0.102 msec was investigated. Before pulse magnetic field stimulus, the red blood cells of test subject were adjoined over ten and the flow of cells was slowed. However after the stimulus in the hand during 10 minutes, the red blood cells adjoined over tens was spreaded out each other and its motion was fast. Also the red blood cells of left hand unstimulated by pulse magnetic field were spreaded out each other, even though the right hand was stimulated during 10 minute. It prove that the rouleau formation of red blood cells can be improve in the whole body in spite of stimulus in the hand because the blood is flowing a whole body.

The changes in the blood flow in the peripheral vascular system under strong pulsed magnetic fields (pMF) were studied by digital infrared thermal imaging (DITI). After pMF stimulus temperatures in stimulated area were commonly increased in both groups of age and gender. In order to reduce heat generated from coil in pMF stimulus system plastic moldings were fabricated, so that certain distance was kept between stimulus system and the skin and to prevent direct contact to the skin. It is believed that skin temperature is increased by internal electromagnetic energy stimulated the peripheral vascular system by non-contact method.

In this paper, we describe the design and implementation of time-varying magnetic field stimulator. Novel design for power supply part to generate high repetitive magnetic field for very short time(less than $300{\mu}s$) was achieved. Using the novel designed power supply part and the circular type coil probe, we've achieved high magnetic field up to 1.2 Tesla in 20Hz repetition rate.
