- Attrecomet 1y agoAnd entirely unimportant for our maps' orientations. Why would we even flip maps? They aren't oriented along the magnetic poles right now!
- nomel 1y agoDepends on your definition of minor. As is, you cannot use magnetic north to navigate, alone, in the east and west of North America. It's 20 degrees off in Oregon, and nearly 40 in northern Alaska. This is something you quickly learn in boy scouts, by getting lost in the woods, if you live on the coast. But, considering it takes 1,000 to 10,000 years to flip, nobody involved in this will be surprised when they look at their compass. They'll have remembered their local correction from when they were children.
