Scientists believe the magnetic field is generated deep inside the Earth where the heat of the planet's solid inner core churns a liquid outer core of iron and nickel. The solid inner core is thought to be a mass of iron about the size of the moon that is heated to several thousand degrees Fahrenheit.
