WebEarth's magnetic field is shaking things up once again. Sloshing liquid iron in Earth's outer core—which lies roughly 1,900 miles (3,200 kilometers) below us—generates our … WebWe know from paleomagnetic records that the intensity of the magnetic field decreases by as much as ninety percent at the Earth's surface during a reversal. But those same paleomagnetic records also show that the field intensity can vary significantly without resulting in a reversal.
