Magnetic Field
In aviation, the magnetic field refers to the Earth's magnetic field, which is used for navigation purposes. The magnetic field is created by the movement of molten iron in the Earth's core and is not aligned with the geographic poles. The magnetic field lines run from the magnetic north pole to the magnetic south pole and are used by aircraft to determine their heading. The magnetic field is measured in units of Gauss or Tesla and can be affected by local variations in the Earth's magnetic field, such as those caused by magnetic anomalies or the presence of ferromagnetic materials.
