Scientists in Britain have been keeping an eye on where the Earth's magnetic north pole is. It's not fixed like the geographical North Pole; instead, it's like a wandering star. Recently, they found ...

But robotic and crewed explorations have determined that the field is non-existent today. Planetary magnetic fields are created by what is known as a dynamo effect, where a magnetic field is created ...

Physicist Walter M. Elsasser and geophysicist Edward Bullard separately propose between 1946 and 1949 that Earth’s magnetic field is a self-sustaining dynamo generated by the movement of fluid ...

which keeps the liquid metal moving through the magnetic field. The so-called Coriolis force also plays a role in sustaining the geomagnetic dynamo. Our planet's spinning motion causes the moving ...

Earth's magnetic field is generated by mixing of the molten iron in the fluid outer core, driven by changes in density as as the inner core slowly solidifies, which creates a dynamo effect.

BEIJING -- A new analysis of samples collected by China's Chang'e 5 mission has revealed that the moon possessed a weak yet still running dynamo magnetic field approximately 2 billion years ago.

Theoretical and computational astrophysics, including solar and stellar convection, magnetic dynamo action within stars, turbulence in many settings, and helioseismology. Central to this is ...

But it would be large enough that other astrophysical processes, like mixing and dynamo amplification, could latch on to that seed field and generate the magnetic fields we see today. This is only ...

used computer simulations and principles of paleomagnetism to estimate the age of Mars's global magnetic field, or dynamo, the Harvard Gazette noted. Steele and her team proposed that Mars's ...

The Dynamo's name begins ... between the ends of an electrical conductor that moves perpendicular to a magnetic field. He then built the first electromagnetic generator, called the Faraday ...
