本文研究了静磁场暴露对血流的影响。本文主要讨论刚性容器内的定常流动，并回顾了现有的理论解，每一个理论解都基于一些简化的假设。结果的开发，检查和比较，显示如何磁流体动力学相互作用降低流速，并产生跨血管壁的电压。这些影响被发现是中等的磁场，如那些用于磁共振成像。在这种情况下，一个非常简化的解决方案，制定忽略壁的电导率以及感应磁场，被证明是合适的。
This paper investigates the influence of static magnetic field exposure on blood flow. We mainly focus on steady flows in a rigid vessel and review the existing theoretical solutions, each based on some simplifying hypothesis. The results are developed, examined and compared, showing how the magnetohydrodynamic interactions reduce the flow rate and generate electric voltages across the vessel walls. These effects are found to be moderate for magnetic fields such as those used in magnetic resonance imaging. In this case, a very simplified solution, formulated by neglecting the walls conductivity as well as the induced magnetic fields, is proven suitable.
