A rotating magnetic field system has been developed to determine the sign of magnetic moment by means of the beta-ray-detected nuclear magnetic resonance method. The rotating magnetic field is obtained using two crossed Helmholtz-like coils at right angles. The phase angles of the alternating currents for the two coils are shifted by 90 degree. Thus the resulting magnetic field is circularly polarized. By the adjustment of the phase-angle difference, a right- or left-circularly polarized magnetic field is produced. Productions of right-or left-rotating magnetic fields including a linear component were confirmed using pickup-coils.A performance of the system was studied with spin-polarized 20F nuclei at the Research Center for Nuclear Physics, Osaka University. The obtained sign of magnetic monet for 20F is positive and in agreement with the reported one.

已经开发了旋转磁场系统，以通过β射线检测到的核磁共振方法来确定磁矩的迹象。使用两个交叉的Helmholtz样线圈以直角获得旋转磁场。两个线圈的交替电流的相角移动90度。因此，所得的磁场是圆极化的。通过调整相角差，产生右或左两极的磁场。使用拾音器固定的右或左旋转磁场（包括线性成分）的生产。在大阪大学研究中心研究了系统的性能。获得20F的磁性莫奈的符号为正，并且与报告的磁力符号一致。
