overall magnetic field的意思|示意

The magnetic field of overall space displacement current excited at any point is always proved tobe zero.

本文证明了在似稳恒条件下，全空间的位移电流在任何一点激发的磁场恒为零。

In short, the Sun's large-scale magnetic field is taken to be self-sustaining, so that the solar-activity cycle it drives would be maintained with little overall change for perhaps billions of years.

简单来说，就是太阳的巨大磁场被用来进行自我维持，所以，由其驱动的太阳活动周期将会在几十亿年的时间里维持整体上维持极小的变动。

The closer the wires the better the cancellation and the smaller the overall magnetic - field energy.

越接近线圈,抵消越明显,总磁场强度越小.
