mag·ne·to·sphere

(măg-nē′tō-sfîr′)

A region surrounding a planet, star, or other body, in which the body's magnetic field traps charged particles and dominates their behavior.

mag•ne•to•sphere

(mægˈni təˌsfɪər)

n.

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.

[1959]

mag•ne`to•spher′ic (-ˈsfɛr ɪk) adj.

magnetosphere

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.

ThesaurusAntonymsRelated WordsSynonymsLegend:

Noun

magnetosphere - the magnetic field of a planet; the volume around the planet in which charged particles are subject more to the planet's magnetic field than to the solar magnetic field

magnetic field, magnetic flux, flux - the lines of force surrounding a permanent magnet or a moving charged particle
