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.
The wheel operated a pulley system connected to a
dynamo, which
generated electricity that flowed to 12 batteries in Brush's basement.
You are missing the point, which is that the double - cycle magnetic period [whether
generated by planets or by standard
dynamo mechanisms] is not the fundamental process.
They follow naturally from the 122 - yr modulation of the fundamental, single period
generated by the
dynamo.
All the energy to light the lamp is
generated though a human - powered
dynamo, which reminds us of the reel of a fishing pole.
