From my understanding when a magnetic field passes through a coil it generates a current. What prevents us from being able to create a coil that can harness earths magnetic field to generate a current/electricity? Would it need to be huge? Is the earths magnetic field to low? Idk I’ve been thinking about it a lot recently and I just don’t understand why it wouldn’t work.

You need to have the earth spin and the coil be stationary, also the magnetic field of the earth is too weak, and would require very fast rotation speeds
