A few % of the magnetic field comes from the stream of charged particles coming from the Sun. This is why the magnetic field varies greatly in Polar Regions during a sunspot storm.
The majority of the field is generated deep inside the Earth by electrical currents in the liquid part of the outer core. The nett result of these currents generates a magnetic field.
The Curie Temperature of magnetic materials ensures that there are no magnetic materials deep in the Earth.

∙ 13y agoThe earth's magnetic field is caused by the fact that the earth has a moltern iron core. When moltern iron spins it causes an electric field. This causes an electromagnetic field. Some planets are too large or too small for the iron in their core to be molten.

The dynamo theory states that earths magnetic field is created in layers?
In the Dynamo Theory, the magnetic field of the earth is created in the outer core. The fluid contained in the outer core creates and maintains the magnetic field during rotation.
Earths magnetic field does not affect what?
Other planets
Does the earths magnetic field has periodically reversed direction?
Yes. In historical times , clay pots have shown that the earth's magnetic field has reversed.
What gives rise to the Earths magnetic field?
Current flows inside he Earth.
What do scientists think produces earths magnetic field?
Its molten iron core.
The dynamo theory states that earths magnetic field is created in layers?
In the Dynamo Theory, the magnetic field of the earth is created in the outer core. The fluid contained in the outer core creates and maintains the magnetic field during rotation.
What is earths magnetic field called?
It is Earths' "Magnetosphere".
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.
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
How is earths magnetic field used by people and animals?
the earths magnetic signature is a negative polarity signature
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".
What is the region of the earths magnetic field?
magnetosphere
Does the earths magnetic field cause the earth to tilt?
No. Earth's magnetic field does not affect its axis of rotation.
What is another word for earths magnetic field?
= An effect of the magnetic field is "Van Allen radiation belt" =
