New findings on Earth's magnetic field
The well-known sources of the magnetic field that surrounds Earth are the deep inside core and Earth's crust. Earth's mantle, on the other hand, has been considered to be 'magnetically dead' for the most part. Now researchers show that a form of iron oxide can also retain its magnetic properties in Earth's mantle.
