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.
Is earths magnetic field the weakest at its poles?
No, but at the poles the field (because of the orientation of the field lines) offers the least protection.
Compass magnets can only be deflected by electromagnets such as Earth's magnetic field?
This is FALSE. TWICE!The Earths magnetic Field is not Electromagnetic.A compass can be deflected by any Magnet.
Does the earths magnetic field cause the earth to tilt?
No. Earth's magnetic field does not affect its axis of rotation.
What is earths magnetic field called?
It is Earths' "Magnetosphere".
How can somethings magnetic field like a tokamak not affect the earths magnetic field?
Because it is far too small to have any effect. The Earth's magnetic field is thought to be generated thousands of miles underground by moving rivers of iron.
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
What is another word for earths magnetic field?
= An effect of the magnetic field is "Van Allen radiation belt" =
