Geophysicist Daniel Lathrop wants, among other things, to use it to predict when the Earth’s magnetic field will next reverse. ... With the sphere spinning at 45 miles per hour, ...

It was a bloated, tempestuous sphere — twice its current size, glowing with internal heat, and wrapped in a magnetic field fifty times stronger than what it possesses now.

The Earth’s magnetic field is why we are here today. It protects life from harmful radiation from the Sun and many other cosmic events. It is generated in the liquid outer core of our planet ...
