Earth's magnetic field (and the surface magnetic field) is approximately a magnetic dipole, with the magnetic field South pole near the Earth's geographic north pole (see Magnetic North Pole) and the other magnetic field N pole near the Earth's geographic south pole (see Magnetic South Pole). This makes the compass usable for navigation. The cause of the field can be explained by dynamo theory. A magnetic field extends infinitely, though it weakens with distance from its source. The Earth's magnetic field, also called the geomagnetic field, which effectively extends several tens of thousands of kilometres into space, forms the Earth's magnetosphere. A paleomagnetic study of Australian red dacite and pillow basalt has estimated the magnetic field to be at least 3.5 billion years old.

At the North and South Magnetic Poles. Here, the magnetic fields converge on a single point, which makes those points the strongest.

About 100 times stronger than the field here on Earth. Unless that it you're near a sunspot! Then the field can be a 1000 times stronger!

The gravitational field strength is approximately 9.82 Newtons/Kg on earth. For simplicities sake, schools round it to 10.

What is created by the suns magnetic field?

Because the gravity of earth was closer together.


Saturn Magnetic Field?

Yes, Saturn has a magnetic field that is produced by electric currents. I guess that also means it is going to be a real challenge for scientists to enter Saturn in the future.


Prevents charged particles from the sun from reaching the surface?

The Earth is protected from the sun's charged particles by its magnetic field. The Earths magnetic field is generated within its molten iron core. Other examples of planets with magnetic fields include: Mercury, Jupiter, Ganymede (Ganymede is the largest moon in the solar system) , Saturn, Uranus and Neptune.Mercury has a relitivley weak magnetic field. It is so weak that the suns charged particles can reach the surface of Mercury. +++ Also the atmosphere.


Does Jupiter have a magnetic field?

Jupiter has a large, complex, and intense magnetic field that is thought to arise from electrical currents in the rapidly spinning metallic hydrogen interior. The Earth has a strong magnetic field, but Jupiter's magnetic field at the tops of its clouds is 10 times stronger than that of the Earth. Further, the Jovian magnetic field has much higher complexity than that of the Earth, with some aspects of Jupiter's fields having no Earthly counterpart. The intensity and complexity relative to the magnetic field of the Earth is presumably related in some way to the more rapid rotation and larger metallic interior for Jupiter.yes


What are the conditions necessary for a terrestrial planet to have a strong magnetic field?

both a molten metallic core and reasonably fast rotation

it's not


What evidence is there on earth having a magnetic field?

To start if we didnt have a magnetic field we would be fried by the suns radiation. The northern lights are evidence that we have a magnetic field surrounding earth.


Why is Saturns Magnetic field strong?

Is mars magnetic field strong or weak?

no mars magnetic field is not strong because it is far away from the sun than earth.


When is a magnetic field is the strongest on a magnet?

How ferroelectrics are different from ordinary dielectrics?

ferroelectrics have strong magnetic field and also magnetic susceptibility & permeability value are strong (>1) but dielectric have feebly magnetic field & it have lesser value.


Why is the earths magnetic field is important because it?

It's important because it protects us from the suns radiation.


Why does mercury have a strong magnetic field?

That's easy because it doesn't. Mercury's magnetic field is only about 1% that of Earth.


Saturn Magnetic Field?

Yes, Saturn has a magnetic field that is produced by electric currents. I guess that also means it is going to be a real challenge for scientists to enter Saturn in the future.


Can an electromagnet have an aluminum core?

The magnetic field will be not be as strong. It will be weaker.


Why won't the earth get any hotter from the suns rays?

The earth has a solid iron core, which creates an electric magnetic field around us. Only a few of the sun's rays can get through that magnetic field.
