According to my relatively shaky understanding of science, moving a conductor through a magnetic field generates power. And the magnetic field of the earth rotates with the earth. So, if an orbiting object (say, a satellite) orbited in the direction opposite the earth's rotation, and was travelling roughly along the magnetic equator, could that satellite generate power from the magnetic field?

    $\begingroup$ I believe this is off-topic here. How is it about building fictional worlds? It's a simple engineering issue, that's all. also, it was already answered on our sister site: Can the Earth's magnetic field be used to generate electricity? $\endgroup$ – Mołot Dec 23 '16 at 12:26
  • $\begingroup$ A good question, but as Molot says, check out that link to Physics.SE. I'm voting to close this as off-topic. $\endgroup$ – kingledion Dec 23 '16 at 13:41

    $\begingroup$ If framed out in a world building narrative this would be fine and on-topic without question and I don't find the narrative entirely necessary personally. That said you may well get a better answer from Physics. If you are looking at how to use it in an imaginary setting update the question and it should stay or get re-opened. Welcome to the site John.

  • $\begingroup$ @James I disagree. Narrative wouldn't make this on topic. At best, it would make it story-based. $\endgroup$ – Mołot Dec 23 '16 at 16:24
  • $\begingroup$ @Mołot I think that as per the logic given in the answers to this meta post, the question could still be on-topic. $\endgroup$ – HDE 226868 Dec 23 '16 at 16:44
