WebJul 2, 2024 · The researchers hope that a 50-hour data set they’re analyzing now will reveal more detail. Additional observations have recently uncovered magnetic fields extending throughout a second filament. Researchers plan to publish this work soon. The presence of enormous magnetic fields in at least these two filaments provides important new … WebStudy of Earth's magnetosphere began in 1600, when William Gilbertdiscovered that the magnetic field on the surface of Earth resembled that of a terrella, a small, magnetized sphere. In the 1940s, Walter M. Elsasserproposed the model of dynamo theory, which attributes Earth's magnetic fieldto the motion of Earth's ironouter core.
