Magnetic compass. Hand holding a compass against a blue sky. The compass has a free-swinging magnetised needle, which is seen pointing to North on the dial. The dial is graduated in degrees and shows the cardinal points: north (N), south (S), east (E) and west (W). The needle aligns itself with local lines of magnetic force to indicate the direction of the north (shown by the yellow tip) and south magnetic poles.
