WebThe 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." WebOnce the process is going, the existing field acts as the seed field. As a stream of molten iron passes through the existing magnetic field, an electric current is generated through a process called magnetic induction. The …
WebJul 2, 2024 · The Earth’s magnetic field is generated by its iron core. As a metal, iron can conduct electricity. Electricity and magnetism can be thought of as the same force, called electromagnetism. A moving electric field can generate a magnetic field, and vice versa. The Earth’s iron core spins, and so the electric field of the core is in constant motion.
