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.

The coil would have to move relative to the magnetic field, just like it does in real electric generators.
Besides, the Earth’s magnetic field isn’t anywhere near as strong in any one place as the magnets in generators, and the magnets don’t produce the energy – the energy comes from whatever’s spinning the coil.
