(a) The north-seeking pole of a magnet; the pole of a magnet which tends
to point to the north, and whence lines of force are assumed to issue on
their course to the other pole of the magnet.

(b) The North Pole of the earth. Treating the earth as a magnet, and
accepting the above nomenclature the north pole should be termed the
south pole. (See Austral Pole–Boreal Pole.)
