How Does The Magnetic Compass Work

Earth itself is like a giant magnet that creates its own magnetic field. Photo by staff sgt. The earth has an iron core that is part liquid and part solid crystal due to gravitational pressure.

Top How Does The Magnetic Compass Work, A compass is an extremely simple device.

How does the magnetic compass work. A magnetic compass doesnt work near the magnetic dip poles near earths local north magnetic poles or near earths south. Therefore if there is no stronger local field a free spinning magnetic needle will point along the field lines between the earth. It can have between 4 and 32 points. So how does a compass work.

Compasses work so effortlessly because their design allows the magnet to respond freely to earths magnetic field. A compass needle aligns itself and points toward the top of earths magnetic field giving explorers and lost souls a consistent sense of direction. A magnetic compass as opposed to a gyroscopic compass consists of a small lightweight magnet balanced on a nearly frictionless pivot point. A compass works by detecting the earths natural magnetic fields.

The magnet is generally called a needleone end of the needle is often marked n for north or colored in some way to indicate that it points toward north. If it is free to rotate a magnet will align itself with the ambient magnetic field. The north end of a compass is drawn to align with earths magnetic north pole. A magnetic compass will not work near a magnet or any magnetic object.

A magnetic compass doesnt work near the magnetic dip poles near earths local north magnetic poles or near earths south. The simplest compass is a magnetized metal needle mounted in such a way that it can spin freely. A magnetic compass points north because it aligns itself with the magnetic field produced inside earth. When the compass is used with a map compass is leveled horizontally and left for a magnetic needle to find the north.

A magnetic compass will not work near a magnet or any magnetic object. North east south and west and their intermediate points. Bailey courtesy of us air force. Magnetic compass has compass rose or a windrose which is used to display the orientation of the cardinal directions.

The earth has a magnetic field.
