Earth's magnetosphere facts
WebMay 13, 2024 · The Earth’s magnetosphere is a spherical electromagnetic sheath that surrounds the earth and travels through space, protecting us from solar wind and cosmic … Study of Earth's magnetosphere began in 1600, when William Gilbert discovered that the magnetic field on the surface of Earth resembled that of a terrella, a small, magnetized sphere. In the 1940s, Walter M. Elsasser proposed the model of dynamo theory, which attributes Earth's magnetic field to the motion of Earth's iron outer core. Through the use of magnetometers, scientists were able to study the variations in Earth's magnetic field as functions of both time and latitude and longitude.
