  • $\begingroup$ Your question was about dragging a wire through the upper atmosphere rather than just through Earth's magnetic field. Does that other question actually answer your question? If so we should mark this as a duplicate. $\endgroup$

  • $\begingroup$ @BrandonEnright Isn't earth's magnetic field avaliable in the upper-atmoshpere? Anyways, I don't know how to mark this as a duplicate, I might not have unlocked that ability yet with such low reputation. $\endgroup$

  • $\begingroup$ Indeed the Earth's magnetic field is available well beyond the atmosphere of the Earth. It sounded like your question was about generating electricity from the charged particles in the ionosphere, not from the Earth's magnetic field. $\endgroup$

  • $\begingroup$ @BrandonEnright Ah! No, I'm talking about dragging a wire through the magnetic field (to induce the faraday effect) $\endgroup$
