magnetopause
Quick Summary
The magnetopause is the boundary of the magnetosphere, the region around Earth where magnetic phenomena are significant. This boundary, located about 10 Earth radii from the planet's center, is where the pressure of the solar wind balances the pressure of Earth's magnetic field. The magnetosphere is shaped like a comet, compressed on the side facing the Sun and extended into a long tail on the opposite side. This region is crucial in atmospheric science as it influences the behavior of charged particles in the atmosphere due to ionization and Earth's surface magnetic field. The magnetopause current system, also known as the Chapman-Ferraro current system, forms this boundary and influences Earth's magnetic field in space.12

geomagnetic fieldOuter magnetic field…this point is called the magnetopause (break in magnetic field). Outside this boundary magnetic fields and particles are present, but they belong to the Sun’s atmosphere and not to Earth’s. On the nightside the magnetic field is drawn out into a long tail consisting of two lobes separated by a…

EarthThe geomagnetic field and magnetosphere…wind can leak through the magnetopause, the sunward boundary of the magnetosphere, and populate its interior; charged particles from the Earth’s ionosphere also enter the magnetosphere. The magnetotail can store for hours an enormous amount of energy—several billion megajoules, which is roughly equivalent to the yearly electricity production of many…
