Will the polarity of the earths magnetic field change in 2012?
There is no reason to believe that the Earth's magnetic field will change any time soon... or, for that matter, that anything extraordinary is going to happen in 2012.
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.
Can earths magnetic field change directions?
sorry I forgot the answer. dummy!
Why does the earths magnetic field change over time?
The Earth's magnetic field changes over time because that is the way that God makes it.
Will the polarity of the earths magnetic field change in 2012?
There is no reason to believe that the Earth's magnetic field will change any time soon... or, for that matter, that anything extraordinary is going to happen in 2012.
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
How does earths magnetic field change over time?
It changes over time through direction and strength. So therefore Magnetic North becomes Magnetic South.
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 region of the earths magnetic field?
magnetosphere
