应用电磁场理论确定引导磁场下顺磁纳米铁核素（PNINs）的运动规律及理论模型。该数学模型及计算机模拟结果成功地解释了铁磁性药物颗粒在引导磁场的作用下随磁场的变化关系，且铁磁性药物颗粒在外引导磁场的作用下能够在靶部位定位分布。理论结果与文献中已发表的实验结果相吻合。

A theoretical model for the magnetic forces on ferromagnetic drug particles in a guiding magnetic field is established with the consideration of the electromagnetic field theory. Our model shows that the ferromagnetic drug particles can concentrate on the targeted area with the guidance of the outside magnetic field. Both the distribution of the intensity of the guiding magnetic field and the forces on ferromagnetic drug particles are studied numerically. The theoretical results are in goo...
