It is very exciting to see the first polarised images of the black hole in the ... Around the black holes, particles whirling around magnetic field lines give off a polarisation pattern, allowing ...

The images of Sgr A* and M87’s black hole ... The polarization pattern is perpendicular to the magnetic field lines. “By imaging polarized light from hot glowing gas near black holes, we ...

The average Hackaday reader likely knows, at least in the academic sense, what a magnetic field looks like ... produce an approximation of what the field lines would look like on its electronic ...

The observation suggested that as the particles spiral around magnetic field lines, they lose energy more quickly. The changes in brightness have been noted in previous research and recent ...

where some of the planet’s magnetic field lines are open,” Grossman says. “Earth’s magnetic field is kind of like a bar magnet, with field lines running from the North Pole to the South ...

Bar magnets and horseshoe magnets are two of the most common shapes of magnet. The magnetic field is shown by lines with arrows that point from north to south. You can tell how old some coins are ...
