WebJul 6, 2024 · Additional resources. Earth's magnetic field — also known as the geomagnetic field — is generated in our planet's interior and extends out into space, … WebMar 4, 2016 · Very simply. Magnetic field is created by electric currents. The currents are simply charges that are rotating inside the earth. This convection, which is in the plane of rotation of the earth, generates a magnetic field which points to the north. Now why does the core move: because it's hot.
WebBeneath our feet and above our heads, electric currents generate magnetic fields that contribute to the totality of the geomagnetic field measured at an observatory on Earth’s surface. The many physical processes that operate in each geophysical domain give rise to a complicated field that exhibits a wide variety of time-dependent behavior.
