SCIENCE ALERT .... Earth's Magnetic Field on The Verge of Flipping Over? An Expert Explains.
Field flips
* Scientists map and track the overall shape and orientation of the Earth's magnetic field using local measurements of the field's orientation and magnitude and, more recently, models.
* The location of the north magnetic pole has moved by about 600 miles (965 kilometers) since the first measurement was taken in 1831. The migration speed has increased from 10 miles per year to 34 miles per year (16 kilometers to 54 kilometers) in more recent years. This acceleration could indicate the beginning of a field reversal, but scientists really can't tell with less than 200 years of data.
