  • Why is Earth Magnetized and Venus Not? - Sky Telescope
    Such a stratified core would lack the wholesale circulation necessary for a dynamo, so there'd be no magnetic field This might have been the fate of Venus Thanks to churning convection in its liquid outer core, Earth has a substantial magnetic field Blue arrow indicates pole direction; yellow arrow points toward the Sun
  • Solar Mission Reveals New Details About Venus’ Unusual . . .
    Unlike Earth, which has an intrinsic magnetic field from the sloshing, molten material inside its core, Venus generates its magnetic field from the interaction of the Sun’s solar wind with the planet’s ionosphere, the atmospheric region filled with charged atoms Those charged atoms create electric currents
  • Why did Venus not lose its atmosphere without a magnetic field?
    The article explains therefore that although Venus does not have an intrinsic magnetic field, the interaction of the thick atmosphere with the solar winds causes an externally induced magnetic field, that deflects the particles of the solar winds The article suggests, however, that the different magnetic field may mean that lighter gasses are
  • Venus Facts - Science@NASA
    Even though Venus is similar in size to Earth and has a similar-sized iron core, the planet does not have its own internally generated magnetic field Instead, Venus has what is known as an induced magnetic field This weak magnetic field is created by the interaction of the Sun's magnetic field and the planet's outer atmosphere
  • An induced global magnetic field looping around the . . .
    However, the large-scale magnetic field observed over the north polar region of Venus has a bias in the dawnward direction and seemingly unresponsive to the IMF's direction Here we show that besides the draped field, there is a second type of induced global magnetic field at Venus and the dawnward field is only a part of it
  • Venus magnetic field: how did it disappear?
    This “magnetic shield” protects the upper atmosphere, but is much weaker than Earth’s magnetic field One of the most important discoveries of the mission was the observation of the phenomenon of magnetic reconnection in the Venus magnetola, a region where the solar wind interacts with the induced magnetic field
  • Magnetic Field Comparison: Differences between Earth, Sun and . . .
    The Earth has a powerful intrinsic magnetic field essential for life Venus has almost no magnetic field of its own and relies on effects induced by the Sun The Sun generates a dynamic magnetic field that directly influences nearby planetary environments
