In this paper, we present results of a theoretical study of circulation flow in ferrofluids under the action of an alternating inhomogeneous magnetic field. The results show that the field with the amplitude of about 17 kA m and angular frequency 10 s can induce mesoscopic flow with a velocity amplitude of about 0.5 mm s. This mechanism can be used for intensification of drag delivery in blood vessels. This article is part of the theme issue 'Patterns in soft and biological matters'.
本文介绍了在交变非均匀磁场作用下铁磁流体循环流动的理论研究结果。结果表明，幅值约为 17kA·m、角频率为 10s 的磁场可以诱导速度幅值约为 0.5mm·s 的介观流动。该机制可用于强化血管内的药物输送。本文是“软物质和生物体系中的图案”主题的一部分。
