It functions as a pointer to "magnetic north", the local magnetic meridian, because the magnetized needle at its heart aligns itself with the horizontal component of the Earth's magnetic field.

Hi dear ❤️
It functions as a pointer to "magnetic north", the local magnetic meridian, because the magnetized needle at its heart aligns itself with the horizontal component of the Earth's magnetic field. ... The local magnetic declination is given on most maps, to allow the map to be oriented with a compass parallel to true north.
Hope it helps u ☺️
