- Save. A compass may be any device that indicates the magnetic North Pole. It usually consists of a magnetized needle that points to magnetic north. The needle may be suspended in a liquid that allows the needle to turn freely, but is viscous enough to the damp the needle's motion.

PLATE TECTONICS   Answer A compass needle is a tiny … magnet, with a north pole and a south pole. These poles are named after the direction in which they point, so the 'painted end' (north) of a compass needle points north because the needle aligns itself with the earth's magnetic field.

How Compasses Work It is believed that these rotational forces in the liquid iron layer lead to weak magnetic forces around the axis of spin. It turns out that because the Earth's magnetic field is so weak, a compass is nothing but a detector for very slight magnetic fields created by anything. That is why we can use a compass to detect the small magnetic field produced by a wire carrying a current (see How Electromagnets Work).

The Compass The compass is an instrument used for navigation; it generally has a magnetic needle that points toward the earth's magnetic North Pole. The magnetic compass has been in existence for nearly a thousand years and is the most common type of compass.he History of the Compass. Compasses were originally developed when lodestones, a mineral that has naturally magnetized iron ore, were suspended above a board with the ability to pivot and turn.

- The origin of the compass is shrouded in mystery. Certainly the Greeks knew about the attractive properties of magnetism in ancient times. Similarly, the Chinese were probably aware that an iron bar stroked with a lodestone acquired a directional north-south property as long as 2000 years ago.

How Does a Compass Work? 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.How it works.ecause 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. True north. While a compass is a great tool for navigation, it doesn't always point exactly north.

- compass card. noun, Navigation. 1. a circular card with magnets attached to its underside, the face divided on its rim into points of the compass, degrees clockwise from north, or both, and floating or suspended from a pivot so as to rotate freely. When in doubt as to where North is, consult the compass card printed somewhere on the chart.

Marine Magnetic Compass and its use on Ships The marine magnetic compass at sea is mainly used for steering a course. The compass reading must be accurate, especially on long sea passages, because a error of one or two degrees in a long course can make a difference of thousands of nautical miles in reaching your destination after many days.he Principles of the compass. A Magnetic compass is a critical piece of marine navigational equipment. Simply put, a magnetised needle, suspended freely, points North because of the forces caused by the Earth’s magnetic field. Once North is known, the other directions are easily found.

Who Invented the Compass? Despite being created for spiritual use, early compasses proved equally valuable for navigation. They were constructed primarily with lodestone, which is a unique type of mineral magnet that automatically aligns with the Earth's magnetic fields.

The Compass Gyroscopic compasses are aligned to the true North Pole and have a needle that spins in relation to the rotation of the earth. They are often used by ships or aircraft so that any local magnetic equipment doesn't interfere with navigation. Thus, they can quickly adjust to movements. This type of compass is usually set to point at true north, based on the direction of a magnetic compass, and then periodically checked with a magnetic compass to assure accuracy. The earliest compasses were most likely invented by the Chinese in around 1050 BCE. They were created first for the purposes of spiritual life or developing a feng shui environment and then later used for navigation.

Facts and History of the Compass Earliest compasses were made of lodestone, a particular form of the mineral magnetite. The first compass was a lump of lodestone that was tied to a rope and left to hang freely. Other were also made from lodestone but were shaped like a spoon or a ladle whose handle was made to point south.

Finding a New Compass ACT is phasing out Compass, a popular but controversial college placement test that colleges use to determine whether students need to take remedial courses. Community colleges and nonselective four-year institutions rely heavily on Compass and Accuplacer, a similar test from the College Board. Both assessments are low-cost, computerized and relatively quick ways of assessing students’ abilities in reading, writing and mathematics.
