Vortex rings are pretty cool, and electromagnetism even cooler. Now, a team of physicists have found a way to combine the two phenomena, creating the electromagnetic vortex cannon. In fluids ...

Vortex Ring: A toroidal region of rotating fluid characterised by a closed-loop configuration of vorticity. Reynolds Number: A dimensionless parameter that quantifies the ratio of inertial to ...

For thirty years, scientists have theorized that it should be possible to create electromagnetic “focused doughnuts” not topologically dissimilar from the vortex rings that form naturally in ...

Imaging quantized vortex rings in superfluid helium to evaluate quantum dissipation. Nature Communications , 2023; 14 (1) DOI: 10.1038/s41467-023-38787-w Cite This Page : ...

Vortex rings are not the only unusual signs of activity recently spotted at Mount Etna. On July 20, a new vent opened up in the Bocca Nuova crater, Behncke wrote on Twitter.

This decayed monopole opens a “vortex ring” that flips the magnetic charge of any other monopole passing through its center, creating an “anti-monopole.” ...

Since vortex rings also retain their shape as they dissipate, they can carry chemical payloads over longer distances -- an advantage over other methods -- that will make firefighters safer as they ...

The volcano, one of Europe’s most active, has been spewing volcanic vortex rings at a rapid pace. But that doesn’t mean a big explosion is on the way, one expert says.
