its made from a really small magnet
point to the magnetic north :)
Due to earth's spinning and rotation, it also behave as a magnet. That's why compass (magnetic needles) show directions as alike poles attracts and like repel each otherg

That's a permanent magnet. After all, the compass doesn't need an electrical current, right?That's a permanent magnet.

The three types of needle points are: ballpoint, sharp needles, and wedge needles. Each of these needles affect fabrics differently. Use ball points for knit fabrics, sharp needles for woven fabrics and wedge needles for vinyl and leather fabrics.

Compass needles are permanent magnets. in response to the Earth's magnetic field, the compass needle will point toward the geographic North Pole.
Steel contains a large proportion of iron which affects compass needles.

The magnetic needles of the compass align with earths magnetic field coming off the polar ice cap.
Used to tip gold pen points, compass needles and clock bearings, electric light filaments and in metal alloys for high temperature uses
the first compass was made from wood
The first compass was made out of cork and a piece of metal.
the first compass was made in A.D. 1087
The compass was made in 1300.
He found that Earth has a magnetic field also known as magnetosphere
