Experimental generation of vortex rings often involves moving a piston through a tube, resulting in a vortex ring being generated at the tube exit. A generation geometry that has been cited as a ...

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.

Scientists have created vortex rings of light. The ring’s surface is illustrated in transparent purple and a hollow core is shown in orange.

But the biggest vortex rings on Earth are not made by dolphins or humans. Volcanoes sometimes emit huge ring shaped clouds of steam and gas up to 200 metres in diameter.
