Does venus have a magnetic field?

Why doesn't Venus have a magnetic field ? In part because of its slow rotation (243 days) and its predicted lack of internal thermal convection, any liquid metallic portion of its core could not be rotating fast enough to generate a measurable global magnetic field. read more

Today, the only magnetic field Venus may have comes from the interaction between Venus's upper atmosphere and the solar wind. The interaction causes electric currents to flow in the upper atmosphere which then create a weak magnetic field that streams behind the planet like a comet's tail. read more

Venus is a rarity among planets – a world that does not internally generate a magnetic field. Despite the absence of a large protective magnetosphere, the near-Venus environment does exhibit a number of similarities with planets such as Earth. read more

The magnetic field of Venus is about 10 times smaller as the earth's magnetic field. The shape of the magnetic field is also different. Earth has a more sharp magnetotail facing away from the sun and Venus has a more comet shaped magnetotail. read more

The magnetic field of Venus is about 10 times smaller as the earth's magnetic field. The shape of the magnetic field is also different. Earth has a more sharp magnetotail facing away from the sun and Venus has a more comet shaped magnetotail. During the reconnections most of the plasma is lost in the atmosphere. read more
