Origins of Earth’s magnetic field remain a mystery

WebDec 31, 2003 · Scientists have known for some time that the Earth's magnetic field is fading. The field is mainly dipolar - but there are anomalies. Like a Kryptonite-challenged Superman, its strength has steadily and mysteriously waned, leaving parts of the planet vulnerable to increased radiation from space. Some satellites already feel the effects. The geomagnetic field changes on time scales from milliseconds to millions of years. Shorter time scales mostly arise from currents in the ionosphere (ionospheric dynamo region) and magnetosphere, and some changes can be traced to geomagnetic storms or daily variations in currents. Changes over time scales of a year or more mostly reflect changes in the Earth's interior, particula… critical risk factors business plan example https://plurfilms.com
