Planets with a magnetic field:-
- Mercury (weak field)
- Earth
- Jupiter
- Saturn
- Uranus
- Neptune
Planets with no magnetic field:-
- Venus
- Mars (no field now, but it did have a field once. Some effect is still present in the oldest rocks)
All Planets have cores are made up of heavy metals (Nickel and Iron). The spinning of molten cores cause friction. This constant friction causes the metals' electrons to spin in the same direction, producing the charged currents of opposite magnetic poles. When the core is very dense, the magnetic field is very strong.
Typically, electrons return to spinning opposite each other, as happens when a planet's cooling core slowly solidifies. This cancels out the magnetic effects back to a neutral net charge.
Dynamo theory suggests that convection in the outer core, combined with the Coriolis effect, creates the Earth's magnetic field. The solid inner core is too hot to hold a permanent magnetic field (see Curie temperature) but probably stabilizes those generated by the liquid outer core.
Recent evidence has suggested that the inner core of Earth may rotate slightly faster than the rest of the planet. In August 2005 a team of geophysicists announced in the journal Sciencethat, according to their estimates, Earth's inner core rotates approximately 0.3 to 0.5 degrees per year relative to the rotation of the surface.
What else can I help you with?
Saturn Magnetic Field?
Saturn has a weak magnetic field compared to other planets like Earth or Jupiter. Its magnetic field is primarily generated by the motion of its metallic hydrogen interior. The magnetic field is not well-aligned with the planet's rotation axis, causing irregularities in its magnetic environment.
What planets have a magnetic field?
Earth, Jupiter, Saturn, Uranus, and Neptune. Other planets (Mercury, Venus, and Mars) have magnetic fields too, but they are too tenuous to be detected from anyplace but the surface and don't protect from solar radiation.
What planet has a large angle that exists between this planets magnetic field and its rotation axis?
Uranus.
Can other planets besides the earth have a magnetosphere?
The magnetosphere is the region around a planet where the solar wind is significantly altered due to the magnetic field of the planet. Planets with a magnetic field arising from internal processes are said to have a global magnetic field. A Global magnetic field will produce a magnetosphere. Six of the planets have global magnetic fields, and hence some magnetosphere; Mercury, Earth, Jupiter, Saturn, Uranus, Neptune. Mars did have one, but when the core froze, that ended the geodynamo. Venus, the near twin of Earth, does not have a geomagnetic field and that is quite perplexing. It too lacks a geodynamo and no one knows why. There are remnant magnetic fields for Mars and Venus, but they are too small to have any significant effect on the solar wind. Jupiter and Saturn have huge magnetic fields and there are only general theories as to what causes them. Uranus has a middling magnetic field, more in the range of Earth's field. The moon has no significant field. We have no idea whether Pluto does or not, but it would be unlikely.
The largest of the Gas Giant planets is?
Jupiter is the largest of the Gas Giant planets in our solar system. It is known for its massive size and intense magnetic field.
Does mars have a gravity magnetic field?
Mars has gravity, as do all planets, but not a magnetic field.
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).
Does Eris have a magnetic field?
No, Eris does not have a magnetic field. It is a dwarf planet located in the outer solar system and does not exhibit any magnetic field like some other planets do.
Which planets do have a magnetic field?
Neptune, Uranus, Saturn, Jupiter, and Earth all have magnetic fields. Mercury has a very weak magnetic field.
Did others planet magnetic field meet the earth magnetic field?
Planets are too far from each other to have any observable interaction of their 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.
Which planet has a magnetic shield?
All planets have magnetic fields. I believe that in most cases, this magnetic field can act as a shield.
Which planets have a magnetic force?
The planets within our solar system that have a magnetic field are: Earth, Jupiter, Mercury (though it is weak), Saturn, Neptune, and Uranus.
What does Mercury's magnetic field affect?
it affects the other planets and its rotation
Which planet has the strongest magnetic field?
Scientists believe Jupiter has a liquid metallic hydrogen core which allows it to form a strong magnetic field. Trapped magnetic particles form radio waves which are amplified by the planet's many moons and which are released into space.
Why does the earth have a magnetic field when some planets don't?
The Earth's magnetic field is generated by a process called the dynamo effect, which is driven by the movement of molten iron and nickel in its outer core. Not all planets have the necessary conditions, such as a molten core and sufficient rotation, to generate 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"?
