Magnetospheric → It is formed from "magnet" (from Greek "magnetis lithos", meaning magnet stone) and "spheric" (from Greek "sphaira", meaning sphere). The word describes the region surrounding a planet where magnetic forces are present, resembling a sphere.
Think of 'magnet' as the force that attracts and 'spheric' as the shape of a sphere, helping you remember that 'magnetospheric' refers to the magnetic field surrounding a planet.
