The points of the compass compzss the vectors by which planet -based directions are conventionally defined. A compass rose is primarily composed of four cardinal directions northeastsouthand west each separated by 90 degreesand secondarily divided by four ordinal intercardinal directionsnortheast, southeast, southwest, and northwesteach located halfway between two cardinal directions.

Some disciplines such as meteorology and navigation further divide the compass with additional vectors. Within European tradition, a fully defined compass has 32 'points' and any finer subdivisions are described in fractions of points.

Compass points are valuable in that they allow a user to refer to a specific azimuth in a colloquial fashion, without having to compute or remember degrees. In the mariner's exercise of boxing the compassall thirty-two points of the compass are named in cmpass order. By the middle of the 18th century, the point system had been wuat extended by using half- and quarter-points to give a total of directions.

Either form is easily understood, but alternative conventions as to correct usage developed in different countries and organisations. Compass roses very rarely named the fractional how to get rid of sun blisters on lips overnight and only showed small, unlabelled markers as a guide for helmsmen.

The table below shows how each of the directions are named. The first two columns give the number of points and degrees clockwise from north. The third gives the equivalent bearing to the nearest dompass from north or piont towards east or west. The "CW" column gives the fractional-point bearings increasing in the clockwise direction and "CCW" counterclockwise.

The final three columns show three common naming conventions: No "by" avoids the use of "by" with fractional points. The traditional compass rose of eight winds and its wind and wind derivatives was invented by seafarers in the Mediterranean Sea during the Middle Ages with no obvious connection to the twelve classical compass winds of w ancient Greeks and Romans. This Italianate patois was used to designate the names of the principal winds on the compass rose found in mariners' compasses and portolan charts of the 14th and 15th centuries.

The "traditional" names of the eight principal winds are:. Local us variations are far more numerous than listed, e. Portolan charts also colour-coded the compass winds: black for the eight principal winds, green for the eight half-winds, and red for the sixteen quarter-winds.

There are no irregularities to trip over; the closest principal wind always comes first, the more distant one second, for example: north-by-east is " Quarto di Tramontana verso Greco "; and northeast-by-north is " Quarto di Greco verso Tramontana ".

A magnet is what makes a compass point north -- the small magnetic pin in a compass is suspended so that it can spin freely inside its casing and respond to our planet's magnetism. A compass needle aligns itself and points toward the top of Earth's magnetic field, giving explorers and lost souls a consistent sense of direction. A compass points north because all magnets have two poles , a north pole and a south pole, and the north pole of one magnet is attracted to the south pole of another magnet.

You may have seen this demonstrated by a pair of simple bar magnets or refrigerator magnets pushed end to end. The Earth is a magnet that can interact with other magnets in this way, so the north end of a compass magnet is drawn to align with the Earth's magnetic field. Because the Earth's magnetic North Pole attracts the "north" ends of other magnets, it is technically the "South Pole" of our planet's magnetic field.

While a compass is a great tool for navigation, it doesn't always point exactly north. This is because the Earth's magnetic North Pole is not the same as "true north," or the Earth's geographic North Pole. The magnetic North Pole lies about 1, miles south of true north, in Canada.

And making things even more difficult for the compass-wielding navigator, the magnetic North Pole isn't even a stationary point. As the Earth's magnetic field changes, the magnetic North Pole moves. Over the last century, it has shifted more than miles 1, kilometers toward Siberia, according to scientists at Oregon State University.

This difference between true north and the north heading on a compass is an angle called declination. Declination varies from place to place because the Earth's magnetic field is not uniform it dips and undulates. These local disturbances in the field can cause a compass needle to point away from both the geographic North Pole and the magnetic North Pole. According to the United States Geological Survey, at very high latitudes , a compass needle can even point south.

By using charts of declination or local calibrations, compass users can compensate for these differences and point themselves in the right direction. Got a question?
