Yes - it is a magnet, but I'm not sure what you mean by it being a "true" magnet.

Not Really .The Earth only became a magnetized after a long period of time. .At the Beginingg the Earth was chaotic(that means it was very hot).Therfore it couldnot have been a magnet. The reason is because a certain temperature no material that we know of,can hold magnetism.(Check out the Curie temperature).
Ther reason that the magnetic poles are continually shifting on the Earth is because we have shifting Sea Currents that affects the magnetic poles of the Earth.
Note ; the Core of the earth cannot hold magnetism because its very vely hot.

Not really, an iron bar at either pole weighs a little less than it does on the equator but only because at the poles it is closer to the Earth's centre, not because of magnetic attraction.

i say yes a magnet because if it wasnt... our compass would not work. But the crazy thing is, is that the poles switch at times. and we can see that there is a magnetic field from the northern lights and stuff... thats cause of magnetism i think...
