WebA sketch of Earth's magnetic field representing the source of Earth's magnetic field as a magnet The north pole of Earth is near the top of the diagram, the south pole near the bottom. Notice that the south pole of that magnet is deep in Earth's interior below Earth's North Magnetic Pole. WebThe interplanetary magnetic field (IMF) By component can cause asymmetric features in the magnetosphere-ionosphere system and influence the electromagnetic energy input. In this study, we use the Space Weather Modeling Framework (SWMF) to study the transient dynamics after a sudden change in the IMF By component exerts on the magnetosphere … Webholes, etc. accompanied by long intervals of southward interplanetary magnetic field (IMF) as in a “magnetic cloud” (Klein and Burlaga, 1982).
