Why do other terrestrial planets have little or no magnetic field?

The core is molten iron (magnetic) and is constantly moving. This moving iron is creating a magnetic field. Some planets don't have molten cores, therefore don't produce this. This process was also kickstarted by the suns solar flares.

Differentiate Jovian planet from terrestrial planet?
The four Jovian planets in our solar system are Jupiter, Saturn, Uranus and Neptune. The four terrestrial planets are Earth, Venus, Mars and Mercury. The difference between the Jovian planets and the terrestrial planets is that Jovian planets are enormous and made of gasses and ices while terrestrial planets are relatively small and made of rocks and metals. Other differences are that terrestrial planets have high densities, rotate slowly, have no moons or magnetic fields and have thin atmospheres (Earth is an exception because it has a moon and a magnetic field), while Jovian planets have low densities, rotate rapidly, have many moons and a magnetic field and have thick atmospheres.
Does earth's magnetic field only affect other planets?
No. Earth's magnetic field only affects earth, not other planets.
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.
Can a planet have a quadrupole magnetic field?
Yes - several planets have magnetic fields that do not even vaguely resemble Earth's current field.
What other planets are likely to have visable northern lights?
Only planets that have an active iron core. Only planets with a magnetic field
What does the presence of a magnetic field on Earth compared with other terrestrial plants indicate?
Plants don't have a significant magnetic field. Perhaps you mean "planets"?

What do you mean by magnetic?
Terrestrial magnetism is the study of magnetic field on earth.
What do you mean by terrestrial magnetism?
Terrestrial magnetism is the study of magnetic field on earth.
Does earth's magnetic field only affect other planets?
No. Earth's magnetic field only affects earth, not other planets.
Does mars have a gravity magnetic field?
Mars has gravity, as do all planets, but not a 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.
What planets aren't magnetic?
Not all of the planets within our solar system have a magnetic field. Venus and Mars are the only ones that don't have a magnetic field (all other planets do have one).
What do you mean by magnetization?
Terrestrial magnetism is the study of magnetic field on earth.
What does the earth's magnetic field not affect?
other planets
Earths magnetic field does not affect what?
Other planets
Which planets do have a magnetic field?
Neptune, Uranus, Saturn, Jupiter, and Earth all have magnetic fields. Mercury has a very weak magnetic field.
