What is the venus magnetosphere?

Answer 1

Magnetosphere

The area around the Earth that extends beyond the atmosphere is called the Magnetosphere. The Magnetosphere begins at approximately 1000 km and extends thousands of kilometers into space. the sun and the Earth's magnetic field create this layer. Ions are trapped in the Van Allen radiation belts. when the particles in the belts collide with particles in the upper atmosphere, visible light known as aurora appear. The visible light we see near the North Pole is called the aurora borealis, also known as northern lights.

A comet-shaped cavity or bubble around the Earth, carved in the solar wind. This cavity is formed because the Earth's magnetic field represents an obstacle to the solar wind, which is a supersonic flow of plasma blowing away from the Sun. As a result, the solar wind flows around the Earth, confining the Earth and its magnetic field into a long cylindrical cavity with a blunt nose. Since the solar wind is a supersonic flow, it also forms a bow shock a few earth radii away from the front of the cavity. The boundary of the cavity is called the magneto pause. The region between the bow shock and the magnetise is called the magneto sheath. The Earth is located about 10 earth radii from the bluntness front of the magnetise. The long cylindrical section of the cavity is called the magneto tail, which is on the order of a few thousand earth radii in length, extending approximately radially away from the Sun. See also Solar wind; Sun.

The magnetosphere has been extensively explored by a number of satellites carrying sophisticated instruments. The satellite observations have indicated that the cavity is not an empty one, but is filled with plasmas of different characteristics. The Earth's dipole magnetic field is considerably deformed by these plasmas and the electric currents generated by them. See also Van Allen radiation.

All other magnetic planets, such as Mercury, Jupiter, and Saturn, have magneto spheres which are similar in many respects to the magnetosphere of the Earth.
the region surrounding a planet, such as the earth, in which the behaviour of charged particles is controlled by the planet's magnetic field

Answer 2

The magnetosphere protects a planet from solar winds or solar radiation by its magnetic fields produced by its iron core. A planet can only have a magnetosphere if its core consists mainly of iron or metal.

Answer 3

No, Mercury has a weak one, Venus has an even weaker one, Mars only has scattered remnants of one, Jupiter has one 10 times stronger, Saturn's is slightly weaker than Earth's, Uranus's and Neptune's are about the same as Earth's but undergo cycles dependent on their interaction with the solar wind.

Answer 4

The magnetosphere is caused by a magnetic field generally accepted to be generated by the rotation of electrically conductive liquid material (probably iron rich) at or around the centre of the earth.

This magnetic field extends beyond the surface of the earth into space and has a profound effect on the charged particals streaming in from the sun. These particles have an electronic charge because they are ions. When they interact with the magnetic field they move away from the direct path toward the middle of the earth and are bent toward a path to the magnetic poles. The aurora are a result of these energetic particles smashing into our atmosphere.

The overall effect of the ionosphere is that it provides us with an umbrella against the harmful effects oif ionising radation from the sun.

Answer 5

the outer region of Jupiter's magnetic field

Answer 6

Magnetopshere is the magnetic field sphere that surrounds the earth. It prevents most of the particle from the sun in damaging the earth.

Answer 7

Mars doesn't have a global magnetic field. So there should not be a magnetosphere.

Answer 8

Excruciating weak.
