The Magnetic CompassOverviewThe magnetic compass was an important advance in navigation because it allowed mariners to determine their direction even if clouds obscured their usual astronomical cues such as the North Star. It uses a magnetic needle that can turn freely so that it always points to the north pole of the Earth's magnetic field.

The earth's surface is covered by an invisible magnetic field. The north and south poles are aligned with the earth's axis. Therefore, magnetic objects, like the needle of a compass, will align itself along the north-south axis.1 Magnetic compasses evolved from using lodestones. Lodestone is a type of magnetic mineral called magnetite.

A compass is a magnetometer used for navigation and orientation that shows direction in regards to the geographic cardinal points.For the structure of the compass, it will show the diagram called compass rose in showing the 4 main directions: East (E), South (S), West (W) and North (N). The angle increases in the clockwise position. North corresponds to 0°, so east is 90°, south is 180° and ...

Magnetic North Pole is actually magnetic south pole and vice versa. Gyrocompass points to true poles. Modern liquid compasses use lamp oil, mineral oil, white spirits, purified kerosene, or ethyl alcohol as a dampening fluid. On the maps, rose-of-winds is usually printed in colors that will be visible in the conditions of lesser visibility.

Magnetic Material. A magnetic material placed in a magnetic field (H) has a magnetic induction (B), measured in teslas (T), expressed by Equation [8.44], where μ0 is the permeability of free space (4π×10−7TmA−1) and the magnetisation, (M=m/V), is the magnetic moment (m) per unit volume (V) of the material (Oberteuf, 1974).
