Mercury, Earth, Jupiter, Ganymede, Saturn, Uranus, and Neptune, for example, exhibit intrinsic magnetospheres. A magnetosphere is classified as "induced" when , or when the solar wind is not opposed by the object's magnetic field. In this case, the solar wind interacts with the atmosphere or ionosphere of the planet (or surface of the planet ...
This magnetic field is induced by an interaction between the ionosphere and the solar wind, [78] [79] [page needed] rather than by an internal dynamo as in the Earth's core. Venus's small induced magnetosphere provides negligible protection to the atmosphere against solar and cosmic radiation.
Components of the induced magnetosphere are shown. Venus is known not to have a magnetic field. [46] [47] The reason for its absence is not at all clear, but it may be related to a reduced intensity of convection in the Venusian mantle. Venus only has an induced magnetosphere formed by the Sun's magnetic field carried by the solar wind. [46]
The Venusian diameter of about 7,500 miles (12,000 km) is just a tad smaller than Earth's 7,900 miles (12,750 km). "Venus and Earth are often called sister planets because of their similarities in ...
At the same time, the gravity at the proposed altitude is 8.73 m/s 2 versus 9.81 m/s 2 on Earth's surface. [citation needed] Venus has an induced magnetosphere from the interaction of its thick atmosphere with the solar wind, and its nearer proximity to the Sun brings it further within the Sun's magnetic field, which decreases the interstellar ...
This magnetic field is induced by an interaction between the ionosphere and the solar wind, [19] [20] rather than by an internal dynamo in the core like the one inside Earth. Venus's small induced magnetosphere provides negligible protection to the atmosphere against cosmic radiation. This radiation may result in cloud-to-cloud lightning ...
The magnetic field of a magnetic dipole has an inverse cubic dependence in distance, so its order of magnitude at the earth surface can be approximated by multiplying the above result with (R outer core ⁄ R Earth) 3 = (2890 ⁄ 6370) 3 = 0.093 , giving 2.5×10 −5 Tesla, not far from the measured value of 3×10 −5 Tesla at the equator.
