Earth's magnetic field is growing weaker
WebAny current (movement of electrical charge) will create a magnetic field. Certain materials are capable of realigning the angular momentum of their electrons, and iron is one of them. When the angular momentum of electrons gets aligned, an external magnetic field is created. Comment. WebJul 20, 2024 · A general weakening of the magnetic field is also associated with reversals. On average, the magnetic field flips every 200,000 to 300,000 years, although the rate is not consistent.
