Is earth magnetic field bigger then Venus?

The Earth's magnetic field and the plant Venus is the same size. Scientist say that Earth and Venus are twin plants.


Does the moon have a stronger magnetic field than the earth?

Venus does not have a magnetic field.


What is the magnetic field of Venus's?

Venus has a small magnetic field created by the interaction of its ionosphere and the solar wind. This is different from most of the intrinsic planetary magnetic fields (those generated by planetary cores) that are commonly spoken about. Venus either lacks an intrinsic magnetic field or it has one that is in the midst of a polarity reversal.


Who has the strongest magnetic field between Earth Venus and Jupiter?

Jupiter.


Is Venus electromagnet?

No. Venus has no magnetic field.


What Has a magnetic field equal to that of Earth?

Nothing. More - the sun, Jupiter. Less - the moon, Venus.


What planet is the weakest in the magnetic field?

The weakest part of Earth's magnetic field is near the magnetic North and magnetic South poles. This is where magnetic field lines intersect with the Earth, and where you are most likely to see auroras during periods of high solar wind activity.


Does Uruguay have a magnetic field?

The earth as a single object has a magnetic field. If Uruguay is part of the earth, it shares the earth's magnetic field.


There are no auroras on Venus because it?

No, as it has no magnetic field.


Is Venus a permanent magnet?

No.-----The earth has an important magnetic field.No, Earth would lose its magnetic field if its molten iron core were not moving. Scientists speculate that Mars had a magnetic field a long time ago but lost it when the planet cooled to the point that its core solidified.


What did mariner 2 find?

Mariner 2's mission was to take scientific measurements of Venus. Some of the results included: -Confirming the estimated temperatures measured using instruments on earth -Magnetic measurements suggesting that Venus has no magnetic field (it was later found that it does indeed have a very weak magnetic field) -Improved measurements of Venus' Mass -Refined Estimates on Venus' cloud thicknesses.


Why doesn't the moon have a magnetic field?

Venus does not have a magnetic field because its rotational period is very slow. This means that if its core had a liquid metal component, it would not be moving fast enough to generate a field.
