带电

In this paper,some instruments with different functions are combined,and by using the motion of charged particle s in the alternating magnetic field produced with Helmholtz coils,the existence of the induced electric field can be validated directly and easily.

针对磁场变化时激发产生的感生电场很难演示的问题，设计了演示感生电场存在的实验。该实验将不同功能的仪器组合起来使用，通过亥姆霍兹线圈的交变磁场对带电粒子的作用效果，直观说明感生电场的存在

In operation, the outlet air preferably flows past the ionizer needle 34, charging particles remaining in the initially filtered air with an electrical charge such that the particles are attracted to a surface or to each other and generally do not remain suspended within the air.

在操作中，出口空气优选地流经电离子针34，利用电荷使保持在初始过滤空气中的微粒带电，以便使微粒被吸引到表面上或彼此吸引，从而通常不会再保持并悬浮在空气中。
