Geomagnetic field | Definition, Strength, & Facts | Britannica
WEB5 days ago · geomagnetic field, magnetic field associated with Earth. It is primarily dipolar (i.e., it has two poles, the geomagnetic North and South poles) on Earth’s surface. Away from the surface the dipole becomes distorted. Understand Earth's geomagnetic field through the dynamo effect principle.
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.
