The earth core is a giant magnet, magnets have two poles; the magnetism is everywhere in a magnet, but it is stronger at the extremities (that is why a compass will work even if you are far from the poles of the planet)
By the way, the magnetic poles are not exactly on top of the geographic ones. And they drift over time.

Earth's core contains a lot of molten iron. Iron has magnetic properties, hence magnetic fields from pole to pole.

I believe the magnetic fields are caused by the movement of the molten lava around our iron core.
Have you heard of the flip?

magnetic field results from the rotation of the outer core. the outer core is made of liquid material which is metallic in nature. as it rotates it exhibit a magnetic field. the rotation of it is the results from the direction of the magnetic field in the earth surface

hi
no , i am sorry but you are wrong
becaus earth magnetic it came from one side ( from north to south)
north pole like as positive charge (+) and south pole like as negetive charge (-) , then we know that negetive charge (-) pull positive charge (+) , there for the magnetic come from north and pulled to south
thanks
