Kje je sever in kje jug

The direction in which a compass needle points is known as magnetic north. In general, this is not exactly the direction of the North Magnetic Pole (or of any other consistent location). Instead, the compass aligns itself to the local geomagnetic field, which varies in a complex manner over the Earth's surface, as well as over time.

EDIT: Kompasova igla vedno kaze proti severu, saj ne "zazna" neke tocke na vrhu zemlje, ampak se le poravna z lokalnimi magnetnimi silnicami (ki _naj_bi_ tekle priblizno od juga proti severu). In ja, sever ima vedno isti (v naprej dogovorjen) predznak.

EDIT2: Cancel that... A typical compass that is allowed to swing only in the horizontal plane will point in random directions at either the South or North Magnetic Poles. Vir: wiki
