How far does a magnetic field extend
The bow shock forms the outermost layer of the magnetosphere; the boundary between the magnetosphere and the ambient medium. For stars, this is usually the boundary between the stellar wind and interstellar medium; for planets, the speed of the solar wind there decreases as it approaches the magnetopause. The magnetosheath is the region of the magnetosphere between the bow sho… Web29 sep. 2024 · The first thing to understand about the magnetic field is that, even if it weakens, it's not going to disappear — at least, not for billions of years.
