A team of researchers at the Brazilian Center for Physics Research is studying the motion of vortex domain walls — local regions of charge that collectively store information via their configuration — driven by magnetic fields in ferromagnetic nanowires, which are configured in a straight line with an asymmetric Y - like branch.

Such charged particles twirl and gyrate around the magnetic field lines created by the vast magnetic systems that surround the sun and Earth.

Physicists aim to solve this mystery by mapping the coronal loops: streams of hot, glowing plasma that follow magnetic field lines...

Over time they build a more detailed magnetic map by learning to recognise variations in the strength and direction of the field lines, which are angled more steeply towards the poles and flatter at the magnetic equator.

That means, the team reports in an upcoming issue of The Astrophysical Journal, that the masers are following magnetic field lines, and therefore magnetic fields are controlling the star's evolution by pulling away material that otherwise would have been captured by the star's gravity.

The lobes consist of the regions in which Earth's magnetic field lines are directly connected to the magnetic field carried by the solar wind.

«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.

And unlike many other subatomic particles, neutrinos have no charge, so they travel in a straight line from their source without being deflected by the magnetic fields around stars.

Anything that nudges the spins of electrons that line up with the Earth's magnetic field will change the energy of those spins by a small amount.

On the other hand, if the electrons are pulled apart, the magnetic force becomes dominant, but so weak in absolute terms that it's easily drowned out by ambient magnetic noise emanating from power lines, lab equipment and the earth's magnetic field.

Researchers produce such heating by aiming microwaves at the electrons gyrating around magnetic field lines — a process that increases the thermal energy of the electrons, transfers it to the ions through collisions, and supplements the heating of the ions by neutral beam injection.
