Cruise along a magnetic field line and see how the ionosphere's charged material also interacts with Earth's own magnetic field.

沿着磁力线航行，看看电离层的带电物质是如何与地球磁场相互作用的。

A field carries energy and passes it on to other charged materials by exerting electric forces.

场携带能量，并将其传递给材料 其他的则通过施加电力来充电。

Today we learned how all objects with net charge generate electric fields that affect all other charged materials.

今天我们了解到，总费用的项目 它生成影响其他带电材料的场。

And he was right: an electric field is a measurable effect generated by any charged object. A field carries energy and passes it on to other charged materials by exerting electric forces.

他是对的：电场是任何带电物体产生的可测量效应。电场携带能量并通过施加电力将其传递给其他带电材料。
