本文通过实验及理论分析,对Ni纳米线在旋转磁场下的运动行为进行研究。Ni纳米线的旋转运动分为同步旋转和异步旋转两种形式。通过受力分析结合量纲比较的手段得到,本文研究范围内流体惯性作用、纳米线运动惯性作用的影响可以忽略,而磁场力矩和流体力矩是控制纳米线旋转运动的主要因素。建立了纳米线旋转运动的控制模型,并得到了区分同步旋转和异步旋转运动的判据。分别针对同步旋转运动和异步旋转运动进行分析,对比不同参数对纳米线运动的影响。
In this paper, experimental and theoretical analysis of Ni nanowires in the rotating magnetic field under the action of the study. Ni nanowire rotation is divided into synchronous rotation and asynchronous rotation of two forms. The force inertia and the inertia of the nanowire can be neglected. The magnetic field torque and the fluid torque are the main factors that control the rotation of the nanowire. The control model of the rotation of the nanowires was established and the criterion of distinguishing between synchronous rotation and asynchronous rotation was obtained. The analysis of synchronous rotation and asynchronous rotation are respectively carried out to compare the effects of different parameters on the movement of nanowires.
