This question already has an answer here:

If I launched a Satellite into orbit and dropped a silver wire caged in carbon fiber with aerodynamic wings (for support), would the Faraday effect of the wire traveling through earth's electromagnetic atmosphere (as the satellite orbits earth) generate a lot of electricity?

Also, would the wire being in the atmosphere eventually pull the satellite back down to earth?

  • $\begingroup$ 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. $\endgroup$ – Brandon Enright May 28 '13 at 2:20
  • $\begingroup$ @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. $\endgroup$ – Albert Renshaw May 28 '13 at 2:33
  • $\begingroup$ 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. $\endgroup$ – Brandon Enright May 28 '13 at 2:37
  • $\begingroup$ @BrandonEnright Ah! No, I'm talking about dragging a wire through the magnetic field (to induce the faraday effect) $\endgroup$ – Albert Renshaw May 28 '13 at 2:47
