The earth has a liquid iron outer core and a solid iron inner core. Circular currents form in the liquid iron outer core and this results in a magnetic field. Since the earth spins, there tends to be a larger number of eddies or currents that orient themselves with the spinning axis of the earth. This results in our magnetic field that is generally oriented to our north and south poles.

the magnetic field has two poles, north and south, that attract the opposite, but not the same. and when you put iron shavings around a magnet, you can see the force field. the Earth has two poles as well, North pole and South pole. if it was possible to put iron shavings around the Earth, you would see a force field close to the force field of stick magnets or any other magnet, for that matter.

It is formed due to the spin of our planet. There is a continual energy increase, due to rotation, as one moves from either pole to that of the plane of our planet's equator. These forces of rotation move in opposite direction to each other, which is the reason winds move in opposite directions in the two hemispheres of our planet. This force is called the Coriolis (sp) Effect. When these opposite moving forces meet through the plane of our planet's equator they cause a great shearing through the plasma area (an area where outer electrons are free of mass bonding). This shearing action forms an electrical field, which field forms a magnetic one at right angles to it. It is the magnetic field formed that gives rise to earth's magnetic field.

from the core it sends out a magnetic field because its the densest part of the earth. The higher away from the core, the weaker the force is.
