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.

∙ 12y agoBecause the earth has a magnetic field that roughly aligns with the geographical north and south. The magnetic north pole is not exactly on the north pole of a globe, but it is close enough for most people. North on the magnet is actually a negative side of a magnet, and opposites attract.

∙ 11y agothe magnet can detect the magnetic field around the earth and north is the strongest and that is why the arrow always poits north on a compass

of the Earth's magnetic field at the place where it's used.

Magnetic iron ore once used as a primitive compass?
Lodestone
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.
A wire in a lamp that is turned on would have a magnetic field around it?
Yes. Any current will produce a magnetic field. Note that such a field might be hard to detect, for example with a compass - since the AC current used in homes changes directions 50 or 60 times per second. Since this is much faster than the compass needle can follow, it will only show the average magnetic field, which is zero.
Does a compass needle point north because of earth's magnetosphere?
It points north because of Earth's magnetic field. I believe the term "magnetosphere" is used mainly for outer space.
Why does a compass needle not point to the geographic North Pole?
The Compass needle not points towards north when placed near iron objects or any magnetic substance(an object which is attracted by a magnet). Edit; Apart from the above, the molten core of the Earth induces circulating currents that place the North Magnetic Pole in Canada and not at the Geographic North Pole; and for that matter the South Pole similarly. It is both intriguing and fortunate that the Geographic and Magnetic Poles are so close together. Edit: It also has a problem pointing north if you're directly above either Magnetic pole.
How navigators and sailors used magnetic compass in preparing root?

During the Sung dynasty Chinese sailors used a navigators compass to extend trade to what areas of the world?

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 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!
What is the impact of the compass on society?
One impact of the magnetic compass on society in ancient time: It enabled sailors to navigate accurately when there was no land or stars in sight. I am deeply frightened of bananas. The magnetic compass was first invented by the Chinese around 1100 AD. It was originally used not to navigate, but as a fortune-telling instrument.
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.
What device was used by sailors to determine direction?
The Compass-
Function of a magnetic compass?
The function of a magnetic compass is to show the direction toward the magnetic poles of the Earth. It is used as a navigation tool.
When is the annunciator of a remote indicating compass system used?
For synchronising the magnetic and gyro compass elements For synchronising the magnetic and gyro compass elements
Who invented the magnetic compass.?
The magnetic compass was made in China the second century AD. The Norse seamen of around 900 AD had magnetite rock that they used as a magnetic compass.
Who used the first magnetic compass?
china
