‘A new research has
determined that Earth’s north magnetic pole is racing toward Russia at
almost 40 miles (64 kilometers) a year due to magnetic changes in the
planet’s core. The core is too deep for scientists to directly detect
its magnetic field. But researchers can infer the field’s movements by
tracking how Earth’s magnetic field has been changing at the surface
and in space.
Now, according to a
report in National Geographic News, newly analyzed data suggest that
there’s a region of rapidly changing magnetism on the core’s surface,
possibly being created by a mysterious ‘plume’ of magnetism arising
from deeper in the core.’
