You could theoretically use electromagnetic induction to produce power from the planet's magnetic field, but the power output would be very small (at the Earth's surface the field is less than 30microT). Such a generator would likely consume more power to operate than it produces.

If only the earth would oblige us by providing us with an alternating magnetic field then we could, just by setting up coils of wire around the place. But sadly it doesn't - the earth's magnetic field is static. And a magnetic field is not a battery either.

This has already been done by Nicola Tesla, he made lights 25 miles away light up using the earth magnetic field without a physical connection. There is speculation that America is trying to develop it for the death ray. It is suspected Russia did try the concept but it caused such serious weather conditions they dropped the idea.

something has to move thru the mag field to induce electricity. a generator works because a coil of wire is exposed to a moving magnet.

Why should it? It's a magnet.... It's like any other material really - like asking why you can't get electricity from a stone.

ummm..magnets dont power electricty dude.
plus, how do you expect us to drill a cord into the core of the earth?

If you have an answer, the energy companies would like to speak with you.
And then kill you...

you can but you have to place an induction coil on the moon
