I don’t mean that any given magnetic field is unchanging, I mean that the principles are stable and well-understood. We never see magnetic fields just randomly change with no reason or else navigation and all kinds of other technologies would be fucked forever.

The earth’s magnetic field is fluid and changing, magnetism is affected by electrical current or heat.
