Good question, it is actually extremely important, this is because it protects the earth from harmful solar flares that would otherwise cause havoc with our electrical appliances. If you have heard of the northern lights and wondered how and why this happens then the reason is that the magnetic field acts the same as a bar magnet and the magnets force goes from the north to south poles and so this allows the solar flares to enter the atmosphere and when it enters the atmosphere it creates the northern lights.
Hope this way helpful in some way
It is Earths' "Magnetosphere".

The equator
That of bar magnet..
The Magnetosphere
the earths magnetic signature is a negative polarity signature
Compasses use the magnetic field to navigate always pointing North.
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
earths magnetic field is generated by the circulation of liquid metal.

= An effect of the magnetic field is "Van Allen radiation belt" =
No. Earth's magnetic field does not affect its axis of rotation.
