Which side is the north pole of a magnet?

If I want my glass exposing to the north pole of a magnet, does anyone have any suggestions on which side the north pole of a magnet is?

Thanks in advance for any suggestions

Arbitrary

The north pole is an arbitrarily defined convention based on the orientation of the Earths magnetic field.

The best way to check the polarity of a magnet is to check it against a reference magnet for which the polarity is known.

The Earth basically supplies the original reference magnet.
