WebKristian Birkeland determined that large-scale ionospheric currents were associated with the aurora. He deduced this from his surface magnetic field measurements in the polar regions at the beginning of the twentieth century. He suggested that these “auroral currents” originated far from the Earth and that they flowed into and away from the ... WebThe article currently states: Pairs of parallel Birkeland currents can also interact; parallel Birkeland currents moving in the same direction will attract with an electromagnetic force inversely proportional to their distance apart (note that the gravitational force is inversely proportional to the square of the distance); parallel Birkeland currents moving in …

There has to be some fundamental … WebKristian Birkeland In the early 1900's the Norwegian physicist Kristian Birkeland took expeditions into the Arctic Circle to study the Aurora. He found that magnetometers changed direction when the aurora appeared. This implies that there must be electric currents flowing high in the atmosphere. Birkeland theorized that the solar wind is a current …
