In early 2014, scientists have discovered that the Earth's magnetic field has been weakening for some time. This could eventually lead to the switching of the Earth's magnetic poles.
The north and south poles have changed places many times in the past.
Magnetic variation or magnetic reversal.
Other planets
Yes. In historical times , clay pots have shown that the earth's magnetic field has reversed.
Current flows inside he Earth.
Its molten iron core.
No, but at the poles the field (because of the orientation of the field lines) offers the least protection.
It is Earths' "Magnetosphere".
Yes.
It is made by the movement of the earths core and magma field
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.
because it has the hydro electric power to control the earths magnetic field
the earths magnetic signature is a negative polarity signature
earths magnetic field is generated by the circulation of liquid metal.
It is Earths' "Magnetosphere".
magnetosphere
No. Earth's magnetic field does not affect its axis of rotation.
= An effect of the magnetic field is "Van Allen radiation belt" =
The Earth's Magnetic field.
