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.
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.
How do magnetics stripes show the history of earths magnetics field?

What is earths magnetic field called?
It is Earths' "Magnetosphere".
How would the history of reversals show itself on the ocean floor?
"Stripes" of alternating magnetic field in the basalt rock of the seafloor.
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 region of the earths magnetic field?
magnetosphere
