For most animals, not at all.
There was a theory that pigeons might be able to detect it, but that seems to be false.
the earths magnetic signature is a negative polarity signature
No. Earth's magnetic field does not affect its axis of rotation.
magnetic field.
iron
No. Earth's magnetic field only affects earth, not other planets.
Other planets
the earths magnetic signature is a negative polarity signature
No. Earth's magnetic field does not affect its axis of rotation.
It is Earths' "Magnetosphere".
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.
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
One navigation guide for animals during migration is the earths magnetic field. Many animals are sensitive to the magnetic fields and use them in navigation. The invention of cellphones with their towers are beginning to cause issues with some migrations due to the altered magnetic field around them.
earths magnetic field is generated by the circulation of liquid metal.
