Mars no longer has a magnetic field. Look at earth for a moment. The earth's magnetic field is generally thought to be the product of dynamo action associated with motion (currents) in the molten fluid core of the earth. Other planets that have magnetic fields are, in general, thought to have this same or a similar source for their fields. Mars no longer has a molten core. Our studies have revealed that there are parts of the crust of Mars that have been magnetized. We see that these areas have a residual magnetic field that has been left as an "impression" of the original magnetic field of the red planet. And that field has changed polarity at different times over the period when Mars still actually had a natural magnetic field and it magnetized portions of the crust. A link to the Wikipedia article on Mars is provided.

∙ 14y agoNo unfortunately for us Mars's magnetic field does not have a magnetic field =( which means to terraform mars would be because of the threat of solar winds damaging mars atmosphere, unless we re start Mar's frozen core and make it active (which we think it was stopped when mars was hit by an asteroid larger than the one that hit earth and killed the dinosaurs, except the one that hit mars sheered off the top of Mars's north pole(we think)).
But back to the question, mars does have a strong crustal magnetic field so strong it surpasses earths crustal magnet field BYE FAR!!!! so mars does have one but not a strong or full magnetic field but one none the less.
if you what to learn about terraforming mars and red a good book read Kim Stanley Robinson's trilogy, red mars , green mars, blue mars.

∙ 11y agoSome scientists believe that due to its smaller size Mars cooled far more rapidly than the earth, causing its molten core to solidify. Without the ability of parts of its core to move around, no magnetism is generated.

Does Mars have a Magnetic Field?
yes mars does alond with Saturn and uranus
Hopw many magnetic fields does Mars have?
Mars does not have a global magnetic field like Earth does. It has remnants of and old global field that may have disappeared 500 million years ago. That would have been the end of protection against the solar wind. It would have stripped the atmosphere off and fried most land life.
Do other planets have magnetic fields?
Yes, all of them do, except for Mars and Venus. Neither Mars nor Venus have a "global magnetic field". Mars has only traces of weak magnetism and Venus is probably even less magnetic.Neither plants nor animals have any significant magnetic field.
How and why did mars lose its atmosphere?
Mars had a molten core that eventually cooled. Causing it to loose its magnetic field allowing solar winds and radiation to "wipe out" its atmosphere.
What does a magnetic field for a toroid look like?
Like a doughnut
Does mars have a gravity magnetic field?
Mars has gravity, as do all planets, but not a magnetic field.
Is the planet Mars non magnetic?
Mars has a magnetic field.
Is mars magnetic field strong or weak?
no mars magnetic field is not strong because it is far away from the sun than earth.
Does Mars have a Magnetic Field?
yes mars does alond with Saturn and uranus
Why Mars today lacks a global magnetic field like that of Earth?
Mars is much smaller, and therefore contains much less thermal energy. The lesser thermal energy caused Mars to cool faster than the Earth. Without heat in the core, Mars will not generate a magnetic field (the rapidly spinning core is a dynamo of magnetic energy).
Can earth loose atmosphere when magnetic field changes?
Earth's magnetic field is weaking such as it did on Mars, so are we also going to loose our own atmosphere as mars did?
What is magnetism on Mars?
The magnetic field on Mars is only residual, it collapsed many eons ago.
Why is mars magnetic field really weak?
The exact reason for Mars' weak magnetic field is not fully understood yet, but one possibility is that its core is cooling down and not generating enough heat to sustain a strong magnetic field. Another factor is Mars' smaller size and slower rotation compared to Earth, which may have led to the depletion of its magnetic field over time.
Does mars has magnetic field?
Yes, but it is much less than Earth's.
What is one fact on Mars?
Mars has virtually no magnetic field because the crust below the surface is so thin.
Can you see the northern lights on Mars?
No. The Northern and Southern lights, called aurora, are the result of Earth's magnetic field funneling high-energy particles from the sun toward the poles. Mars does not have a magnetic field and so does not have aurora.
Why does Mars have life on it?
Currently there is no real evidence that there is life on Mars. The atmosphere is too thin and there is not magnetic field to protect against solar radiation. Like the Earth mars might have been in the golden locks position.
