Well, considering the core is iron, the magnetism could come from Magnetite. But that's an hypothesis.

Still, i keep this in mind when thinking about subjects like this: Different universe, different world. Our rules are not necesarily Their rules. Even if we knew everything about our universe, no one knows if all universes are the same. So regardless of how the Earth became what it is today, there's no reason to assume the exact same must have happened with Remnant.
