(Physical Geography) the region surrounding a planet, such as the earth, in which the behaviour of charged particles is controlled by the planet's magnetic field
1. the outer region of the earth's ionosphere where the earth's magnetic field controls the motion of charged particles, as in the Van Allen belts.
2. such a region of another planet.
mag•ne`to•spher′ic (-ˈsfɛr ɪk) adj.
The region near the planet possessing a magnetic field, which determines the motion of the charged particles in this region. Earth, Saturn, Jupiter, Uranus, and Mercury are the solar system planets known to have magnetospheres.
