lets say if you were to suspend a bar magnet freely it wouldn't just swing around. it would line with the north and south pole that's how a compass works

A compass needle points northward due to earths?
magnetic field
A device that uses the Earths magnetic field to indicate witch way north is?
A compass.
What is earths magnetic field called?
It is Earths' "Magnetosphere".
How is the orientation of Earth's magnetism recorded in rocks on the ocean floor?
Earths magnetic orientation is locked into the rock when the rock cools
What causes a compass needle to point to geographic north?
the pole of the compass is attracted to the earths geographic north pole
A compass needle points northward due to earths?
magnetic field
Compass magnets can only be deflected by electromagnets such as Earth's magnetic field?
This is FALSE. TWICE!The Earths magnetic Field is not Electromagnetic.A compass can be deflected by any Magnet.
How does the magnetism in the compass work with the magnetism of earth so that the compass is a useful tool for navigating?
The magnetic needles of the compass align with earths magnetic field coming off the polar ice cap.
How a magnetic compass can be used to find directions on Earths surface?
A compass is an instrument containing a freely suspended magnetic element which displays the direction of the horizontal component of the Earth's magnetic field at the point of observation.
Can magnetic field lines be detected by a compass?
The magnetic field can certainly be detected by a compass.The 'lines' are a handy human invention, and don't really exist, so you could not,say, trace out the lines with a compass, because they're not there.But place a compass next to a wire that's involved in any battery-operated (DC)circuit, and the compass absolutely goes crazy !
A device that uses the Earths magnetic field to indicate witch way north is?
A compass.
What do you have to add to a compass to make it in line with the earths magnetic field?
Nothing. That's exactly what a compass does ... as long as it's free to turn, and there are no ferrous metals or other sources of magnetic fields nearby.
At the earths magnetic north pole it is pointless trying to use a compass to find your way?
yes it is pointless
What cause deviation in a magnetic compass?
The compass needle will only align itself with the magnetic meridian if it is free from all other influences except the magnetic field of earth.This is rarely so, particularly on a ship which constructed on steel. The magnetism induced in the steel by the earths magnetic field causes the compass needle to deviate from the magnetic meridian, by an amount which is called the DEVIATION.
What magnet use in the compass?
non the compass uses the earths magnetic field that is why the north pole and south pole is the most important directions because the north and south pole have the most highest magnetic feilds
Is a compass rose and a compass the same?
No a compass rose is on a map showing all of the Carnal Directions (north South East west) and a Compass is navigational device used to find your direction by using the earths magnetic poles
Why is it hard to read a compass when standing at one of the earths poles?
Because the earths magnetic poles move around from year to year, and even day to day.
