Earth’s inner core solidified sometime after 565 million years ago — just in time to not only save the planet’s protective magnetic field from imminent collapse, but also to kick-start it into its ...

(PhysOrg.com) -- A University of California, Berkeley, geophysicist has made the first-ever measurement of the strength of the magnetic field inside Earth's core, 1,800 miles underground. The magnetic ...

Around 1,800 miles beneath your feet lies a giant, blazing-hot ball of metal. It's the innermost part of our planet, Earth's core. It has a profound impact on your life, though none of us can even ...
Annual to decadal changes in the earth’s magnetic field in a region that stretches from the Atlantic to the Indian Ocean have a close relationship with variations of gravity in this area. From this it ...
Between 2004 and 2016 these SV patches, required by the observational data, have notably increased in magnitude. This change is robustly seen not only in CHAOS-6, but also across a wide range of other ...
Researchers have shown that turbulence, random motion that takes place in the molten metal in the Earth's core, makes a contribution to our planet's magnetic field. To obtain this result, they modeled ...
Figure 2: Map of annual difference of the second time derivative of the vertical component for epoch 2003.5. High-resolution core magnetic-field models like xCHAOS make it possible to investigate core ...
Measurements of the magnetic field at the earth's surface can tell only so much about the dynamo producing it in the planet's core. Geophysicists have now used precise astronomical position data to ...
