Jupiter is surrounded by an enormous magnetic field called the magnetosphere, which has a million times the volume of Earth's magnetosphere. Charged particles are trapped in the magnetosphere and form intense radiation belts.
How strong is Jupiter’s magnetic field?
Its equatorial field strength is about 417.0 μT (4.170 G), which corresponds to a dipole magnetic moment of about 2.83 × 1020 T·m3. This makes Jupiter's magnetic field about 20 times stronger than Earth's, and its magnetic moment ~20,000 times larger.
What planets have a magnetic field?
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. The mechanism that causes their magnetic fields is not fully understood.
What is true about Jupiter’s magnetic field?
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. The magnetosphere extends so far past Jupiter it sweeps the solar wind as far as the orbit of Saturn.
Why does Jupiter have the most 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.
Is Jupiter a failed star?
"Jupiter is called a failed star because it is made of the same elements (hydrogen and helium) as is the Sun, but it is not massive enough to have the internal pressure and temperature necessary to cause hydrogen to fuse to helium, the energy source that powers the sun and most other stars.
Which planet has the second strongest magnetic field?
Jupiter is the largest planet in the Solar System and therefore has the strongest magnetic field.

- Venus. …
- Mars. …
- Jupiter. …

Which planet has highest magnetic field?
Jupiter 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.
How can you tell if a planet has a magnetic field?
A magnetometer is an instrument for measuring magnetic fields. Many spacecraft carry magnetometers to measure the magnetic fields around planets. When a spacecraft makes those measurements, what do the measurements tell us? The planet might have a global magnetic field surrounding it.
Why does Jupiter give off so much radiation?
It is Jupiter's combination of a strong magnetic field, Io's prodigious source, and the magnetic coupling of charged particles to the planet's rapid (10-hour) spin that drives the intense radiation.
