Because the length of the power coil designed is longer than that of the GMM pole, magnetic symmetry is kept well and a higher intensity of magnetic field is obtained under the same current.
设计的线圈长度大于驱动棒长度，不仅保证了驱动棒所处磁场的均匀性，而且在获得相同强度的磁场时减小了稳定工作时的电流。
A ferrous metal pole wheel passing the sensor face changes the magnetic field strength, resulting in an ac voltage being induced in the coil.
当一个铁磁性极轮通过传感器头部的感应磁场时，就会在电感线圈内产生一个交流电压。
