Earth'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.

Feb 17, 2025 · 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, …

Jul 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.

Earth’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.

Feb 17, 2025 · It covers fields from gigantic bodies like the Sun and Earth, as well as those emanating from the movement of neural currents in your brain. It includes your WiFi and cellphone signals, and the...

The geomagnetic field measured at any point on the Earth's surface is a combination of several magnetic fields generated by various sources. These fields are superimposed on and interact with each other.

The geomagnetic field is used to explore the dynamics of Earth’s interior and its surrounding space environment, and geomagnetic data are used for geophysical mapping, mineral exploration, risk mitigation, and other practical applications.

The geomagnetic field of the earth is very similar to that of a large bar magnet placed at the center of the Earth, with its south end oriented toward the north magnetic pole.

Frequently asked questions about NCEI's geomagnetic data and products, descriptions of the Earth's magnetic field, and answers to common questions about the fundamentals of geomagnetic science.

Geomagnetism is one of the oldest geophysical sciences. Geomagnetic fields have been observed and used since ancient times, and are still used for modern applications in navigation and mineral exploration.
