[Workshop From Scratch] was faced with this problem, so he built a motorized magnetic track for his plasma cutter. Thanks to a pair of repurposed electromagnetic door looks and adjustable base ...

Observations of the Hanle effect have revealed the existence of small-scale ‘hidden’ magnetic flux on the quiet Sun. The magnetic-energy density of this hidden flux is much larger than ...

Earth's magnetic field, the only planetary field for which we have good ongoing measurements, changes all the time. But the new information is important, because these small changes reveal hidden ...

Also, because M87*'s magnetic fields drive powerful outflows or "jets," the results hint that Sgr A* could have a hidden and faint jet all of its own. Related: James Webb Space Telescope finds ...

If you've ever watched a flock of birds move in perfect unison or seen ripples travel across a pond, you've witnessed nature's remarkable ability to coordinate motion. Recently, a team of scientists ...
