Magnetic compass. Magnetic compass on a map. The compass has a free-swinging magnetised needle (red and white) pointing to a dial. The dial is gradua- ted in degrees and shows the cardinal points: north (N), south (S), east (E, not clearly seen) and west (W). The needle aligns itself with the local lines of magnetic force to indicate the direction of the north (shown by the red end) and south (shown by the white end) magnetic poles.
