They also have to assume that Mars had
a much stronger magnetic field in the past so that building an intracellular magnetic compass would be an advantage.
Ignitor takes a different approach than ITER, using a much smaller and more compact tokamak (it's radius is 1.3 meters compared with ITER's 6.2 meters) and
a much stronger magnetic field to compress the plasma.
As they report online today in Nature Communications, superflares do seem to be produced by the same process, but they usually occur in stars with
much stronger magnetic fields than the sun's.
Not exact matches
Neutron stars, the extraordinarily dense stellar bodies created when massive stars collapse, are known to host the
strongest magnetic fields in the universe — as
much as a billion times more powerful than any human - made electromagnet.
Neutron stars, the extraordinarily dense stellar bodies created when massive stars collapse, are known to host the
strongest magnetic fields in the universe — as
much as a billion times more powerful than any man - made electromagnet.
They think a very
strong magnetic field, tens of trillions of times the size of Earth's and
much stronger even than a normal pulsar's
field, generates the bursting pulsar's signals.
Rocks below the surface in those spots might contain remanent magnetism from early in the Moon's history, when its
magnetic field was
much stronger than it is now.
If a neutron star is left, it may have a very
strong magnetic field and rotate extremely quickly, emitting a beam of light that can be observed when the beam points towards Earth, in
much the same way as a lighthouse beam sweeping past an observer.
«Instead of a prolonged, comet - like tail, this rough bubble - shape of the heliosphere is due to the
strong interstellar
magnetic field —
much stronger than what was anticipated in the past — combined with the fact that the ratio between particle pressure and
magnetic pressure inside the heliosheath is high,» said Kostas Dialynas, a space scientist at the Academy of Athens in Greece and lead author on the study.
«Most surprising is that the blast wave was still
strong enough to cause significant effects in the atmosphere of Saturn, which is nearly a billion miles from the sun and has a
magnetic field much larger than Earth's,» says Ed Stone of Caltech, chief scientist of NASA's Voyager program.
Charged objects are
much easier to control because electric and
magnetic fields can exert
much stronger forces over them.
Supernova remnants — the leftovers of massive stellar explosions — possess
magnetic fields much stronger than previously thought, recent observations of pulsating X-ray hot spots reveal.
The
magnetic field becomes very concentrated and
much stronger than before.
The influence from direct radiation would be similar, but the planets with a
strong magnetic field would react
much differently to charge particles than a planet like Mars with a weaker
field.
Their measured value is 5 — 10 Gauss,
much stronger than the average 1 Gauss strength of the principal components of the Sun's
magnetic field.
Indeed, sometime after the tenuous gas of the Solar nebula began collapsing into the proto - Sun within its host molecular cloud, a
strong magnetic field developed that was instrumental in transporting rotational energy away from its core region in bi-polar jets of gas so that centrifugal forces created by the nebula's collapse did not grow so
much as to halt continuing gravitational contraction.
This is in part because the equipment runs as
much as $ 1 million to buy and needs to be stored in a specially housed area to protect the rest of a veterinary hospital from its
strong magnetic field.
The influence from direct radiation would be similar, but the planets with a
strong magnetic field would react
much differently to charge particles than a planet like Mars with a weaker
field.
