Interplanetary Magnetic Field (IMF)

The Interplanetary Magnetic Field (IMF) is the magnetic field carried from the Sun into space by the solar wind—a stream of charged particles emitted by the Sun. This magnetic field extends throughout the solar system and interacts with planetary magnetic fields, influencing space weather phenomena such as auroras and geomagnetic storms. The IMF's strength and orientation can vary, especially when solar activity increases, affecting communication satellites, power grids, and navigation systems on Earth. Overall, the IMF is a crucial part of how the Sun’s influence reaches and impacts planets in our solar system.
