The Earth's magnetic field is what makes the common magnetic compass work. From its invention until the advent of newer technologies beginning around the turn of the 20th century, the magnetic compass, together with the sextant and the chronometer, constituted the primary tools of the navigator. Of course, the compass' primary role was to facilitate steering ships on the right heading under conditions where the Sun and stars could not be seen.

Magnetic iron ore once used as a primitive compass?
Yes, magnetic iron ore, such as magnetite, was used as a primitive compass because it has magnetic properties that align with the Earth's magnetic field. When suspended or placed on a floating object, the iron ore would align itself in the north-south direction, indicating the cardinal directions. This provided early navigators with a basic way to orient themselves.
What characteristic of iron would make it a bad material for the housing around a compass?
It could not be used because it attracts magnets and a compass is a specialist form of magnet, utilising the magnetic properties of the earth to give a reading. Compass housings are invariably made of brass, aluminium or plastic.
What is the instrument for telling direction?
A compass will tell you which direction you are traveling in.
What does a dip compass do?
A compass does not point to the North Pole, it aligns itself with the lines of magnetic force at your location. In the Northern Hemisphere you are closer to the North Pole, so the strength from that direction is greater, and the compass "points north". In the Southern Hemisphere, similarly, the magnetic South Pole is closer, and the other end of the compass points to the south Pole. So far so good. But when you are close to either pole, the magnetic field dips into the earth - steeply at the Poles themselves. [Ordinary compasses are counterbalanced a little so the compass needle or card is approximately horizontal. The compass manufacturers divide the earth into five 'balance' zones.] So a dip compass is suspended between two pivots, and will indicate the steepness of the magnetic fields dip. It differs from an ordinary compass.
Does a compass needle point north because of earth's magnetosphere?
A compass needle points north because it aligns with Earth's magnetic field, specifically the magnetic north pole. Earth's magnetosphere is the region around Earth influenced by the planet's magnetic field, but the compass needle is primarily responding to the magnetic field itself.
How navigators and sailors used magnetic compass in preparing root?

Why magnetic compass is used by sailors and navigators to find the direction?
On a magnetic compass, the needle marked North points towards magnetic North, provided there is no ferrous metal nearby. Magnetic North is not the same as geographic North (North Pole). On a metal ship, the magnetic compass has to be adjusted (box the compass) to allow for the metal round the ship. By steering a compass course, allowing for drift caused by the wind and the ebbing and flooding of the tides, a ship should be able to reach a distance port, or at least be with in sight.
What was the name of the stone used by early sailors as a primitive compass?
The stone used by early sailors as a primitive compass was called a lodestone. Lodestones are naturally magnetized rocks that were used to help sailors navigate by aligning with the Earth's magnetic field.
Who first used the compass rose?
The compass rose was first used by early navigators and cartographers in the 14th century to show the orientation of maps and charts. It helped sailors determine direction and navigate the seas accurately using the cardinal and intercardinal directions.
What is a compass north south east and west?
It is called a mariners compass, it is a instrument that shows the North, east, West and South, and is used by pilots and the sailors.
What kind of transportation did cartier use?
They used a ship and a navigator to help them find their destination and the navigators were a magnetic compass and astrolabe (the stars). He could of use the blah blah!
Why is the magnetic compass so important?
The magnetic compass is important for navigation because it provides a reliable way to determine direction, even when other technologies fail. It has been used for centuries by sailors, pilots, and hikers to find their way and can be crucial for safety in unfamiliar or remote locations.
During the Sung dynasty Chinese sailors used a navigators compass to extend trade to what areas of the world?
During the Song dynasty, Chinese sailors used navigators' compasses to extend trade to various regions in Southeast Asia, the Indian Ocean, and even as far as East Africa. This allowed for the development of extensive trading networks and the establishment of Chinese maritime influence in these regions.

Why did the Chinese sailors use a lodestone?
Chinese sailors used a lodestone as a compass for navigation because lodestones are naturally magnetized stones that can align themselves with the Earth's magnetic field. This property allowed them to determine the direction they were traveling in, aiding in their exploration and trade expeditions.
What device was used by sailors to determine direction?
The Compass-
What instrument is used for determining direction?
A compass. The North magnetic pole is in the direction of the N on the compass. Therefore, the North magnetic pole is in fact a magnetic field south pole since it *attracts* the north magnetic field pole of the compass magnet.
