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: Explained | Space
WEBJul 6, 2022 · Earth's magnetic field — also known as the geomagnetic field — is generated in our planet's interior and extends out into space, creating a region known as the magnetosphere.
MagNet: Model the Geomagnetic Field - NASA
WEBDec 15, 2020 · The efficient transfer of energy from solar wind into the Earth’s magnetic field causes geomagnetic storms. The resulting variations in the magnetic field increase errors in magnetic navigation. The disturbance-storm-time index, or DST, is a measure of the severity of the geomagnetic storm.

WEBFeb 14, 2011 · This stereoscopic visualization shows a simple model of the Earth's magnetic field. The magnetic field partially shields the Earth from harmful charged particles emanating from the sun.
Geomagnetic field | Definition, Strength, & Facts | Britannica
WEBSep 28, 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.
Earth's Magnetic Lines - Science On a Sphere
WEBThe blue lines show where the magnetic field dips into the Earth and the red lines show where the magnetic field emerges from the Earth. Where the field lines are horizontal to the Earth, between the red and blue lines, is the magnetic equator shaded yellow.
