TRIVIA BITS … COMPASS

TRIVIA BITS …

COMPASS

Compass

A compass is a navigational device containing a small, free-moving magnet called a needle.

The needle is attracted to the earth's magnetism and swivels on a pivot until one end points to the earth's magnetic north pole. From the knowledge of which way is north, of course, any other direction can be found.

At first only north and south were marked on the dial, but later the other 30 principal points of direction were filled in.

A cardinal point is one of the four principal compass points: north, south, east, and west.
