Sentences with phrase «generate dynamos»

If Lathrop's machine can generate a dynamo and then start flipping direction, scientists might have more insight into what triggers such changes on Earth — and how likely it is that we are headed for another one.
Both forced liquid sodium in cylindrical tanks to flow in a helical pattern — a twisty motion that was enough for the fluid to generate a dynamo.

Not exact matches

Rather than generating their own power via water wheels or electric dynamos, companies can now plug into the newly built electric grid and buy electricity directly from power stations.
Scientists think a dynamo — a rotating, convecting, electrically conducting fluid in a planet's outer core — is the mechanism for generating the planetary magnetic fields.
No dynamo yet, but the device allows the team to generate huge amounts of data very quickly.
Stars like the sun generate powerful internal dynamos as well, and laboratory models filled with superhot metal might be able to re-create them.
The long - held assumption was that it takes a planet the size of Earth to insulate a molten iron core, whose currents and eddies act as a dynamo to generate a magnetic field.
Although dynamos are thought to require large planetary cores, it's possible that the molten cores of these small bodies may have churned vigorously enough to generate magnetic fields, he says.
This magnetized terrain dates back at least 3.7 billion to 3.9 billion years, so the researchers deduce that ancient Mercury had a dynamo in which electrically conducting fluids inside its iron - rich core generated the field.
In fact, the star appears too hot to have the type of stellar dynamo that generates magnetic effects within cooler stars such as our sun.
He suggests that the acceleration of particles in the solar wind — essentially a surface phenomenon — is determined by the strong «dynamo» magnetic field generated deep down in the Sun.
Dynamos are possible because mechanical energy — in this case the movement of the fluid in the outer core — can generate a magnetic field.
This governs the nature of the dynamo that generates magnetic field in the stellar interior and determines the observed large - scale magnetic structure.
At the first close approach, instruments detected a magnetic field, to the great surprise of planetary geologists — Mercury's rotation was expected to be much too slow to generate a significant dynamo effect.
A 2008 University of Toronto study theorized that, more than 4 billion years ago, incoming asteroids applied a gravitational tug to liquids in Mars» core, producing enough of a dynamo effect to generate a temporary electromagnetic field.
Our planet's magnetic field is generated by molten iron swirling around in the planet's outer core around a smaller, solid core — a process that creates a self - sustaining geomagnetic dynamo.
Ordinary stars have magnetic fields generated internally by moving gases acting as dynamos, but neutron stars are packed far too tightly for that.
«The results of our study support the idea that galaxy magnetic fields are generated by a rotating dynamo effect, similar to the process that produces the Sun's magnetic field,» Mao said.
Stellar flares can be four orders of magnitude more powerful, which is thought be due to bigger starspot regions generated by a more efficient dynamo process, because many of the flaring stars rotate faster than the Sun.
Detailing the day of Operation Dynamo — during which a civilian British fleet evacuated some 300,000 trapped soldiers from the beaches of Dunkirk, France — would be tricky enough, particularly with Nolan's old - fashioned analog style taking minimal advantage of computer - generated trickery.
Now the GM division has generated some electricity with a new dynamo: the convertible version of the Cutlass Supreme.
This change may be related to chaotic changes in the dynamo that generates the solar magnetic field.
It is worth noting that Theodor Landscheidt — one of iconoclasts in the «solar - forcing - trumps GHG's» school of European solar physicists — predicted this possible Grand Minimum based on the theory that Gliessberg cycles generated by the Sun's oscillation around it's centre of mass directly affect the Coriolis force perturbing solar plasma flow and the solar dynamo.
Small modular dynamos and origami unfolding heat exchangers can easily be robotically meshed in giant networks to create orbital power farms to generate 800Twatts in near solar orbits and microwave it back to earth or even as far as Mars.
