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.

As the structures are so tiny — each grain is only about the size of a virus — there is only one method with which the nanovortices can directly be observed while they are heated up and cooled down: «A special high - resolution electron microscope at the Ernst Ruska - Centre (ER - C) in Jülich is capable of making magnetic fields on the nanoscale holographically visible,» explains Almeida.

«We found that the energetic plasma signatures occur on high - latitude magnetic field lines that have been «closed» by the process of magnetic reconnection, which then causes the plasma to become relatively hot,» says Dr Fear.

Yet, despite their widespread use, at room temperature only three elements are ferromagnetic — meaning they have high susceptibility to becoming and remaining magnetic in the absence of a field, as opposed to paramagnetic substances, which are only weakly attracted to the poles of a magnet and do not retain any magnetism on their own.

Proton density after laser impact on a spherical solid density target: irradiated by an ultra-short, high intensity laser (not in picture) the intense electro - magnetic field rips electrons apart from their ions and creates a plasma.

«The magnetic field does that at a higher level in the atmosphere, but the gravity field tells us that it's going on a lot deeper, in the middle of the planet, or even deeper than that,» Bolton says.

(2007) that variations in radionuclide production rates on up to multi-centennial time scales are dominated by solar magnetic field variations.
