通电螺线管里的电流产生里一个移动磁场，以非接触的方式驱动车辆。
Electric current in the cable winding generates a traveling magnetic field which pulls the vehicle along without contact. The support magnets form the exciter (i. e. the motor).
在该盘上与转轴同心地放着一有限长的通电螺线管，在盘的边缘均匀对称固定着若干带电金属小球。
In concentric with the shaft of the plate to lay on a finite length solenoid power, the edge of the plate with a number of symmetrical fixed charged metal ball.
当螺线管德通电，飞行员口关闭并全线压力作用于出血口通过对膜片的顶部。
When the solenoid is de-energised, the pilot orifice closes and full line pressure is applied to the top of the diaphragm through a bleed orifice.
给出了一种利用霍尔效应测量螺线管磁场的新方法：用数字电压表取代电位差计等诸多仪器测量霍尔电势差，进而计算出通电长直螺线管内轴向磁场的分布。
Digital voltmeters, instead of voltage meters and other instruments, are used to measure Hull voltage and then to calculate the axial magnetic induction distribution in charged straight spiral tubes.
