On a planet, a species uses magnets (i.e. float in the air) instead of wheels for transportation. Roads are easy enough, just slap some magnets in it, at it works.
But I was wondering about the feasibility of having transportation which uses the magnetic field of the planet to hover above the ground, or off-road transportation. Is it even remotely possible, and if so, how strong will the magnets need to be? The magnetic field is the same strength as Earth's.
