What crucial magnetic structure is carried outward by the persistent solar wind plasma?
Answer
The interplanetary magnetic field (IMF)
The solar wind is defined as a persistent outflow of plasma, superheated gas composed chiefly of electrons and protons, continuously streaming away from the Sun's corona in every direction. A critical aspect of this outflow is that the plasma inherently carries the magnetic field generated by the Sun along with it as it travels throughout the solar system. This structure carried by the solar wind forms what is formally termed the interplanetary magnetic field (IMF), which serves to permeate the entire extent of the solar system.
