A magnetic field is caused by the internal motion of molten rock in the outer layer of a planet's core.
Mars is smaller than the Earth, so it's core has cooled down to the point where the magnetic field has all but shut down.

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.

Is mars magnetic field strong or weak?
no mars magnetic field is not strong because it is far away from the sun than earth.
What creates a planet's magnetic field?
The dynamo. For terrestrial planets, the dynamo is a molten core of nickel-iron. Mercury and Earth have fairly strong dynamos and therefore fairly strong magnetic fields. Venus and Mars do not, and have only weak magnetic fields.
Which planet has craters cliffs and a weak magnetic field?
Mercury :) hope I helped!!
Would it be good to visit a planet with a magnetic field?
We are already on a planet with a magnetic field and yes magnetic fields are what protect the planet from various dangers. Not to mention nearly every planet we have seen has a magnetic field (save venus). It is believed that the magnetic fields of planets save them from solar winds which would otherwise slowly strip the atmospheres of planets by taking out chunks of atoms every time they hit. Mars has an extremely weak (or none according to many scientists) magnetic field and as such the solar winds bash into it and scoop out ions from the planet. Overall conclusion: Yes, you want to visit a planet with a strong magnetic field, it's basically more protection (in theory at least).
Why do materials have magnetic properties too weak to be detected?
Because the intrinsic magnetic field generated by the spin of the electrons around the nucleus is negligible...
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 Auroras?
Auroras are interactions of the planet's magnetic field with the solar wind, exciting particles in the upper atmosphere. Mars' atmosphere is thin and its field weak, so such interactions as there may be would not be visible.
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.
What is the magnetic strength of moon?
The moon does not have a dipolar magnetic field and its external magnetic field is quite weak when compared to that of the Earth.
The weak magnetic field around mercury suggests what?
upcoming magnetic reversal
Which planets do have a magnetic field?
Neptune, Uranus, Saturn, Jupiter, and Earth all have magnetic fields. Mercury has a very weak magnetic field.
What creates a planet's magnetic field?
The dynamo. For terrestrial planets, the dynamo is a molten core of nickel-iron. Mercury and Earth have fairly strong dynamos and therefore fairly strong magnetic fields. Venus and Mars do not, and have only weak magnetic fields.
Where is the edge of a magnetic field?
There is no edge. The field continues on to infinity, but the field gets very weak.
What planet has craters cliffs and a weak magnetic field?
Mercury
Is the moon a source of earth's magnetic field?
No. The source of earth's magnetic field is the molten inner core. The moon due to its proximity of course influences our magnetic field but it is to be considered a "weak effect".
What is meant by the term diamagnetism?
Diamagnetism is weak repulsion by a magnetic field.
