Earth's magnetic field - Wikipedia
WEBEarth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun.
Earth's Magnetic Field: Origin, Structure, and Impact on Humanity
WEBEarth’s magnetic field, also known as the geomagnetic field, is a powerful, vital phenomenon that extends from the interior of the Earth into outer space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun.

WEBAug 16, 2024 · Geomagnetic field, magnetic field associated with Earth. It is primarily dipolar (i.e., it has two poles, the north and south magnetic poles) on Earth’s surface. Away from the surface the dipole becomes distorted. The field is variable, changing continuously, and its poles migrate over time.
Geomagnetic reversal - Wikipedia
WEBA geomagnetic reversal is a change in a planet's dipole magnetic field such that the positions of magnetic north and magnetic south are interchanged (not to be confused with geographic north and geographic south).
Magnetic anomaly - Wikipedia
WEBIn geophysics, a magnetic anomaly is a local variation in the Earth's magnetic field resulting from variations in the chemistry or magnetism of the rocks. Mapping of variation over an area is valuable in detecting structures obscured by overlying material.
