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." Web12 dec. 2003 · 12 Dec 2003. By Robert Irion. Geotangle. Earth's magnetic field forms a complex pattern that occasionally flip-flops--an event captured by this computer simulation.
