Ring current - Wikipedia
WEBA ring current is an electric current carried by charged particles trapped in a planet's magnetosphere. It is caused by the longitudinal drift of energetic (10–200 k eV) particles. Earth's ring current. Schematic view of the different current systems which shape the Earth's magnetosphere.
NASA’s Van Allen Probes Reveal Long-term Behavior of Earth’s Ring Current
WEBMay 19, 2016 · The ring current lies at a distance of approximately 6,200 to 37,000 miles (10,000 to 60,000 km) from Earth. The ring current was hypothesized in the early 20th century to explain observed global decreases in the Earth’s surface magnetic field, which can be measured by ground magnetometers.

WEBMar 8, 2018 · The basic structure and dynamics of the primary electric current systems in the Earth's magnetosphere is presented and reviewed. The implications of understanding magnetospheric current systems are discussed, including …
Ring Current - an overview | ScienceDirect Topics
WEBJan 24, 2012 · The ring current is an electric current that consists of charged particles trapped in the Earth's magnetosphere. It is generated by the movement of these particles in the longitudinal direction, and its intensification during magnetic storms creates a horizontal magnetic field on the ground with an opposite orientation to the Earth's dipole field.
Ring Current - SpringerLink
WEBThe Earth's ring current consists of millions of Amperes of electrical current, encircling the Earth in space near and within the geosynchronous orbit (6.6 Earth radii). It is a feature of the interaction between the magnetized conducting solar wind and the Earth, with its geomagnetic field and conducting ionosphere.
