磁场分布的测量采用基于核磁共振（NMR）傅里叶成像技术的方法进行。通过选择限制核磁共振可观测核的空间分布的物体，可以获得易于解释磁场分布和促进磁体快速振荡的图像。结果显示了用于核磁共振成像的超导电磁磁铁的垫片线圈组的效果。分析了这种测量方法在类似磁体设计的快速摆振中的应用。还观察了靠近磁体的钢板的影响。
Measurement of magnetic field distributions is performed using a method based on the nuclear magnetic resonance (NMR) technique of Fourier imaging. By selecting objects which limit the spatial distribution of the NMR-observable nuclei, images can be obtained which allow easy interpretation of the magnetic field distribution and facilitate rapid shimming of magnets. Results are presented showing the effect of a shim coil set of a superconducting solenoid magnet of the type use for NMR imaging. The application of this type of measurement to the rapid shimming of similar magnet designs is analysed. The effects of steel plates close to the magnet are also observed.
