Magnetosphere

The region of space in which a planet's magnetic field dominates that of the solar wind.

Magnetosphere

The magnetic cavity surrounding the earth, carved out of the passing SOLAR WIND by virtue of the GEOMAGNETIC FIELD, which pre- vents, or at least impedes, the direct entry of the SOLAR WIND PLASMA into the cavity.

Magnetosphere

A magnetosphere is the area of space near an astronomical object in which charged particles are controlled by that object`s magnetic field. Near the surface of the object, the magnetic field lines resemble those of a magnetic dipole. Farther away from the surface, the field lines are significantly distorted by electric currents flowing in the pla....

magnetosphere

a region, beyond the ionosphere, in which the trajectories of charged particles essentially depend on the environmental magnetic field, the effect of collisions being negligible NOTE - Towards the Sun, the outer limit of the Earth's magnetosphere is at a distance of some ten Earth radii. The magnetosphere extends much farther in the opposite direct...

Magnetosphere

is a mostly convex region formed when a plasma, such as the solar wind, interacts with the magnetic field of a body, such as a planet or star.

magnetosphere

magnetosphere 1. The region surrounding an astronomical object; such as, the earth, in which charged particles are trapped and affected by the object's magnetic field. 2. A region between five hundred and several thousand miles above the earth's surface, in which charged particles are trapped by the earth's magnetic field.

Magnetosphere

The region around a planet such as the Earth within which the motion of charged particles is influenced by the planet's magnetic field. The Earth's magnetosphere consists of a dipole field, similar to that of a bar magnet, and a long tail on the night side produced by the interaction of the solar wind with the Earth's magnetic field.

magnetosphere

The region of space in which a planet's magnetic field dominates that of the solar wind. It is distorted into a teardrop shape by the solar wind pushing on the dayside and drawing out a long magnetotail on the nightside. Earth's magnetosphere normally extends about 10 Earth radii on the dayside, whi...

magnetosphere

Volume of space, surrounding a planet, in which the planet's magnetic field has a significant influence. The Earth's magnetosphere extends 64,000 km/40,000 mi towards the Sun, but many times this distance on the side away from the Sun. That of Jupiter is much larger, and, if it were visible, would appear from the Earth to have roughly t...
