Answers
magnetic compass consist of a magnetic needle pivoted at its center and free to rotate a horizontal plane . the needle is fitted in a horizontal box having a glass cover . the compass also has a dial with directions marked on it....
In order to locate the directions at a place , the compass is placed away from any other magnet, or iron pieces or any current carrying wires the compass needle will then point along the north-south directions at that place..
the Earth is a magnet that can interact with others magnets in this way, so the North end of a compass magnet is drawn to align with the Earth earth's magnetic field. Because the earth's magnetic North Pole attracts the "North" ends of other magnets, it is technically the "South Pole" of our planet's magnetic field.
