WebThe Earth, acting just like a very large magnet, also produces invisible lines of force, or magnetic field lines. Earth's field lines start near the South Pole of the Earth, curve … WebIn a sense, yes. The Earth is composed of layers having different chemical compositions and different physical properties. The crust of the Earth has some permanent magnetization, and the Earth’s core generates its own magnetic field, sustaining the main part of the field we measure at the surface. So we could say that the Earth is, therefore, a "magnet."
