Magnetic compass. The compass has a free-swinging magnetised needle (white) pointing to a dial. The dial is graduated in degrees and shows the cardinal points: north (N),south (S),east (E) and west (W). Only N and W are seen here. The needle aligns itself with the local lines of magnetic force to indicate the direction of the north and south magnetic poles | |
