设计、制造和测试了一种产生旋转磁场的新型装置。该系统由一个亥姆霍兹线圈对，它是机械耦合到直流电动机的角速度控制。线圈对产生均匀的磁场;整个系统旋转，使用电刷保持线圈通电。对于沿旋转轴沿着约100 mm的工作空间，磁场强度是均匀的（约5.8 mT）。对于低于10 Hz的旋转频率，系统保持没有不期望的高振幅机械振动。我们验证了该装置的性能进行实验与磁性游泳者。
A novel device to produce a rotating magnetic field was designed, constructed, and tested. The system consists of a Helmholtz coil pair which is mechanically coupled to a dc electric motor whose angular velocity is controlled. The coil pair generates a uniform magnetic field; the whole system is rotated maintaining the coils energized using brushes. The magnetic field strength is uniform (≈5.8 mT) for a workspace of about 100 mm along the rotation axis. The system remains free of undesirable high amplitude mechanical vibrations for rotation frequencies below 10 Hz. We verified the performance of the apparatus by conducting experiments with magnetic swimmers.
