Physicists Observe Trippy ‘Vortex Rings’ in a Magnetic Material For The First Time – ScienceAlert

Wherever you have fluid, there you can also find vortex rings.
Now, scientists have found vortex rings somewhere fascinating – inside a tiny pillar made of a magnetic material, the gadolinium-cobalt intermetallic compound GdCo2.
If you’ve seen smoke rings, or bubble rings under water, you’ve seen vortex rings: doughnut-shaped vortices that form when fluid flows back on itself after being forced through a hole.
The new discovery is the first time vortex rings have been identified in a magnetic material,…
