How strong is the sun's magnetic field?
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.
What causes the magnetosphere to exist?
The magnetosphere exists due to Earth's magnetic field, which is generated by the movement of molten iron in its outer core. This magnetic field extends out into space, forming a protective shield around the Earth that deflects charged particles from the solar wind.
Why is maglev technology currently being developed for launching spacecraft?
Maglev tech is being developed for spacecrafts because the earth is one big magnet with is magnetic field therefore when it goes into space the speed will be easier because it will repel againts earths magnetic field :D
How far does the Earth's magnetic field extend into space?
The Earth's magnetic field extends out into space for tens of thousands of kilometers, forming a region known as the magnetosphere. This region protects the Earth from harmful solar radiation and charged particles by deflecting them around the planet.
Does the moon have a stronger magnetic field than the earth?
No, the moon does not have a global magnetic field like Earth. Some localized magnetic fields have been detected on the moon's surface, but they are much weaker than Earth's magnetic field.
What is the region of the earths magnetic field?
The region of the Earth's magnetic field is called the magnetosphere. It extends far into space and protects the Earth from solar wind particles and cosmic radiation. The magnetosphere is created by the interaction between the Earth's magnetic field and the solar wind.
What is the layer of the earth that influences earths magnetic field?
The outer core of the Earth is responsible for generating the planet's magnetic field through the motion of molten iron and nickel. This movement creates electric currents, which in turn produce the magnetic field that extends around the Earth.
Is earths core a source of earths magnetic field?
Yes.
How are the Earths magnetic field made?
It is made by the movement of the earths core and magma field
Earth's magnetic field results from the spinning of the?
The earths magnetic field results from deep in the earths core. Magnetic conduction from within the earths core is believed to be the cause of this.
Where is earths magnetic fe ild created?
Earth's magnetic field is generated by the movement of molten iron and nickel in its outer core. The rotation of the Earth causes these metals to generate electric currents, which in turn create a magnetic field. This magnetic field extends around the Earth and helps protect it from solar winds and cosmic radiation.
Why do scientists believe that the inner core is the source of earths magnetic field?
because it has the hydro electric power to control the earths magnetic field
What is earths magnetic field called?
It is Earths' "Magnetosphere".
Where does the earth's magnetic field get its power from?
earths magnetic field is generated by the circulation of liquid metal.
What is the magnetic field called?
It is Earths' "Magnetosphere".
Why is earths magnetic field impotant?
The earth's magnetic field is important in that it prevents the sun's solar radiation from killing life on earth by wiping out the earth's atmosphere and deflecting dangerous radiation.
What is an example of earths magnetic field?
Earth's magnetic field is like a giant bar magnet with the magnetic North and South poles located near the geographic North and South poles. This field extends from the Earth's core out into space, protecting the planet from solar wind and cosmic radiation. It is what causes compass needles to point north.
