在本次交流中，研究了磁场中无场线（FFL）形成的理论。结果表明，只需三个麦克斯韦线圈对即可产生 FFL。通过改变施加的电流，FFL 可以任意旋转，同时保持线圈在空间中静止。为了平移，可以使用额外的亥姆霍兹线圈对。这些发现使得能够有效地实现用于最近开发的称为磁性粒子成像的成像方法的场生成单元。
In this communication, the theory of field-free line (FFL) formation in a magnetic field is investigated. It is shown that an FFL can be generated by only three Maxwell coil pairs. By varying the applied currents, the FFL can be arbitrarily rotated, while keeping the coils static in space. For translation, additional Helmholtz coil pairs can be used. These findings enable efficient realization of a field generating unit for a recently developed imaging method named magnetic particle imaging.
