Have you tested?
My understanding and testing and reading indicate that the
'n' end of a compass needle is defined as the North Seeking
End, shortened to 'noth pole' which makes geographic
NORTH a Magnetic SOUTH pole. Counterintuitive.
I'll think about that as you raise a good point. I do know that I have
a couple of horseshoe kiddies magnets marked with N and S, and the north
end of a compass needle points to the "N" pole.

Likely. At least nitially. At least for Europeans."
