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.
