Which terrestrial planet has the strongest magnetic field?
Jupiter. After the Sun, Jupiter has by far the strongest and biggest magnetic field in our solar system — it stretches about 12 million miles from east to west, almost 15 times the width of the Sun. (Earth's, on the other hand, could easily fit inside the Sun — except for its outstretched tail.)
Which terrestrial world has the strongest magnetic field quizlet?
Why does Earth have the strongest magnetic field among the terrestrial worlds? It is the only one that has both a partially molten metallic core and reasonably rapid rotation.
Which worlds have the strongest magnetic fields?
Jupiter, Saturn, Uranus, and Neptune all have magnetic fields much stronger than that of the Earth. Jupiter is the champion- having the largest magnetic field.
Which terrestrial planets have a magnetic field?
At the present time, only the Earth and Mercury appear to have a significant dipole magnetic field. However, the Moon, and possibly Mars, appear to have had ancient planetary dynamos.
Which terrestrial planet has the weakest magnetic field?
Of the planets in our solar system, the one with the weakest magnetic field is Mercury.
Is Earth’s magnetic field stronger than Venus?
“If there is a magnetic field at Venus, it has to be 100,000 times weaker than Earth's mag-netic field.”
Which of the terrestrial worlds has the strongest magnetic field group of answer choices Moon Mercury Earth Mars Venus?
Why does Earth have the strongest magnetic field among the terrestrial worlds? A) It is the only one that has a metallic core. B) It rotates much faster than any other terrestrial world.
Which of the terrestrial planets has the weakest magnetic field?
Answer and Explanation: Of the planets in our solar system, the one with the weakest magnetic field is Mercury. This is excluding the two planets of Mars and Venus that… See full answer below.
Does Uranus have a strong magnetic field?
With all of these poles and its crazy tilt, the magnetic field on Uranus varies a lot from place to place. In some places in the southern hemisphere of Uranus the magnetic field is only 1/3rd as strong as Earth's field. However, in some parts of the North the field on Uranus is almost four times as strong as Earth's!
Why is Earth’s magnetic field stronger than Mars?
Earth's, by comparison, varies up to around 65000 nanotesla, or more than 40 times stronger than Mars'. Earth's magnetic field is supported by an internal dynamo; Mars must once have had a dynamo, which would have magnetized its rocks, but then the dynamo shut down.
Which planet has the weakest magnetic field?
Of the planets in our solar system, the one with the weakest magnetic field is Mercury.
Which planet of the below has the strongest magnetic field group of answer choices Earth Mars Mercury Saturn?
Jupiter, the largest planet in our solar system, also has the largest magnetic field, generating a magnetosphere larger than the Sun.
Is Jupiter’s magnetic field stronger than Earth’s?
Some 20,000 times stronger than Earth's magnetic field, Jupiter's magnetic field creates a magnetosphere so large it begins to avert the solar wind almost 3 million kilometers before it reaches Jupiter.
Does Neptune have a strong magnetic field?
Neptune, the eighth planet from the sun, has vivid blue clouds and fierce windstorms, but also a badly behaved magnetic field. The field is 27 times more powerful than Earth's and sits at an angle on the planet, changing chaotically as it interacts with the solar wind.
Why did Mars lost magnetic field?
Researchers believe that Mars once had a global magnetic field, like Earth's, but the iron-core dynamo that generated it shut down billions of years ago leaving behind only patches of magnetism due to magnetised minerals in the Martian crust.
Where is the magnetic field the strongest and why?
It is strongest at the poles. So, what are magnetic poles? Magnetic poles are opposite ends of a magnet where the magnetic field is strongest.
Which of the four terrestrial planets has the strongest magnetic field?
Which of the four terrestrial planets has the strongest magnetic field, Mars, Mercury, Venus, or Earth? The Earth, by far.
Is Jupiter’s magnetic field stronger than the Suns?
Extending beyond Jupiter's moons, the Jovian magnetic field is the strongest in the solar system, except for the Sun's. The field dominates an expansive region called the magnetosphere – the largest structure in the solar system.
How strong is Saturn’s magnetic field?
The magnetic field strength at Saturn's equator is about 21 μT (0.21 G), which corresponds to a dipole magnetic moment of about 4.6 × 1018 T•m3. This makes Saturn's magnetic field slightly weaker than Earth's; however, its magnetic moment is about 580 times larger.
Does Venus have a magnetic field like Earth?
Unlike Earth, which has an intrinsic magnetic field from the sloshing, molten material inside its core, Venus generates its magnetic field from the interaction of the Sun's solar wind with the planet's ionosphere, the atmospheric region filled with charged atoms.
Is the core of Mars Dead?
Some four billion years ago, the core of Mars became inactive, its magnetic field disappeared, and the solar wind stripped the atmosphere away. With our magnetic field intact, our planet will remain blue and alive for the foreseeable future.
Will Earth ever lose its magnetic field?
In fact, paleomagnetic studies show the field is about as strong as it's been in the past 100,000 years, and is twice as intense as its million-year average. While some scientists estimate the field's strength might completely decay in about 1,300 years, the current weakening could stop at any time.
Where is the world’s largest magnetic field?
The current world record holder seems to be the National High Magnetic Field Laboratory (NHMFL) in Los Alamos, USA, with a magnetic field strength of about 100T (so about two million times higher than the Earth's magnetic field).
Where are usually the magnetic force strongest?
The magnetic field generated by any magnet is always strongest at either pole. The magnetic force is equally as strong at both the north and south pole.
Is Earth’s magnetic field stronger than Jupiter?
Jupiter hosts the most powerful magnetic field of all the planets in our solar system, cranking out a field close to 20,000 times stronger than Earth's.
Does Jupiter or Saturn have a stronger magnetic field?
Jupiter's equatorial field, at 4.3 gauss, is more than 20 times stronger than Saturn's.
How strong is Uranus magnetic field?
Thus, in an astrophysical context, the field of Uranus may be described as that of an oblique rotator. The dipole moment of 0.23 gauss R3U, combined with the large spatial offset, leads to minimum and maximum magnetic fields on the surface of the planet of approximately 0.1 and 1.1 gauss, respectively.
How strong is Mars magnetic field?
Mars' current magnetic field is very weak, with strengths of at most about 1500 nanotesla. Earth's, by comparison, varies up to around 65000 nanotesla, or more than 40 times stronger than Mars'.
Why does Jupiter have such a strong magnetic field?
Jupiter's outer core is also thought to be responsible for its enormous magnetic field, though it is liquid hydrogen crushed by intense pressure into a metallic form that generates the magnetism rather than iron compounds.
What destroyed Mars?
NASA pointed out that Mars had a thick atmosphere shortly after it was formed, and most of the composite in its atmosphere was carbon dioxide. However, due to the lack of magnetic field protection, the majority of the Martian atmosphere was destroyed by the strong solar wind, and escaped to space (Carlisle, 2015).
