The magnetic compass is the most familiar compass type. 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.

Magnetic compass, in navigation or surveying, an instrument for determining direction on the surface of Earth by means of a magnetic pointer that aligns itself with Earth's magnetic field.

The magnetic compass is working with the principle of Earth's Magnetic Field and shows the magnetic north and south. The simplest form of compass consists of a magnetized needle free to rotate in a horizontal plane.
