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.
No 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.
Some 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.
Earth is the three plant from the sun and mars is the fourth plant from the sun
Yes but it is gone now
Mars's gravity is 38% of Earth's gravity.

yes mars does alond with Saturn and uranus
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.
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.
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.
Like a doughnut
Mars has gravity, as do all planets, but not a magnetic field.
Mars has a magnetic field.
no mars magnetic field is not strong because it is far away from the sun than earth.
yes mars does alond with Saturn and uranus
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?
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).
