Sentences with phrase «very strong magnetic fields»

With very strong magnetic fields and very fast rotations, some neutron stars blast beams of electromagnetic radiation from their poles, and if Earth is in the path of those beams we can detect the signals as regular «pulses» — hence the name pulsars.

When neutron stars form they will be spinning rapidly and have very STRONG magnetic fields (109 to 1012 times the Sun's).

As expected, superconductivity is destroyed in the presence of very strong magnetic fields (in the case of this material above 12 Tesla).

Superconductivity and magnetic fields are normally seen as rivals — very strong magnetic fields normally destroy the superconducting state.

In 1930, physicists Werner Heisenberg and Hans Heinrich Euler predicted that very strong magnetic fields could change the polarity of light waves in a vacuum (where polarity refers to the orientation of the light's electric and magnetic fields).

Now, scientists using the European Southern Observatory's (ESO) Very Large Telescope (VLT) say they may have observed this effect in the light coming from a neutron star — a cosmic object with a very strong magnetic field.

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.

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.

That outer layer would have dragged against the liquid interior, generating friction and a very strong magnetic field (SN Online: 12/4/14).

The other obvious problem is that you are essentially trying to operate one very strong magnetic field within another even stronger one.

«To mechanically twist or pull a particle requires a very strong magnetic field.

In the single - atom qubit used by Morello's team, and which Tosi's new design applies, a silicon chip is covered with a layer of insulating silicon oxide, on top of which rests a pattern of metallic electrodes that operate at temperatures near absolute zero and in the presence of a very strong magnetic field.

The Jovian system is a busy place: Jupiter has a very strong magnetic field, a faint ring system and over 60 rocky moons orbiting around it.

Not exact matches

The pulsar's fast rotation and strong magnetic field work together to accelerate electrons and other particles to very high energies.

What makes this model unique is that a magnet in the center of the inner sphere provides a strong magnetic field, while the rotation of this core drives the flow of the conducting liquid very effectively.

Superconducting state is very responsive sensitive to magnetic fields: strong magnetic fields destroy it, but and superconductors expel the magnetic field completely.

«If there is a magnetic field which is very strong, you don't need a piece of glass or a prism to refract the light,» says team member Silvia Zane at University College London.

It also has to use very strong microwaves and magnetic fields to reach the sample, but these processes are invasive and can affect delicate bio-samples, just like the microwave in your kitchen, particularly when trying to see the molecular structure of liquids.»

Strong magnetic fields, coupled with a very hot and dense plasma provide a candidate method for creating a lightsaber.

For certain applications, there is indeed a desire for a kind of compensator, namely for a relatively low magnetic flux to match conditions as under very strong fields.

We know that for energies of modest to intermediate energy, the culprit or the source of the acceleration appears to be the shock front that surrounds a [an] expanding supernova blast wave; that is to say, we have a star that undergoes a massive cosmic explosion [and] drives a strong shock wave out into the surrounding interstellar medium, and the gas around the shock wave, and all the magnetic fields associated with it are capable of accelerating particles to very high energies; and also incidentally magnifying and amplifying the magnetic field associated with that shock front and giving a lot of x-ray emission and radio emission and so on, and so we've understood that.

[4] Very little is known about the origin and characteristics of the magnetic fields that were present in our galaxy when it was young, so it is unclear whether they have grown stronger over time, or decayed.

The magnetic field becomes very concentrated and much stronger than before.

The strong magnetic fields inside these remnants accelerate protons to very high speed, creating cosmic rays.

Large changes in cosmic rays are documented in response to magnetic - field variations (the Laschamp event of about 40,000 years ago is especially prominent) with no corresponding change in climate, so any cosmic - ray influence on the climate must be very small (a weak correlation can be obscured by noise; a strong control is almost always visible «by eye,» and clearly is absent).

[Response: In this estimation, you divided a small amplitude ba an even smaller (the 22 - year Hale cycle is not very strong, and not even discernable in the sunspot record, even though we have reasons to believe it exists since the magnetic fields flip), thus not a very reliable method.

What will happen to the Earth remains to be seen and predicted because nobody has developed any program or any models of terrestrial response — they are based on this period when the sun has maximum activity — when the sun has these nice fluctuations, and its magnetic field [is] very strong.
