What exactly is the curl meaning in vector calculus? or Can someone explain the curl meaning in simpl

Wow, thanks everyone! The paddlewheel/whirlpool analogies totally clicked for me. I checked out 3Blue1Brown’s video, and it’s way clearer now.

Still kinda fuzzy on how curl applies to electromagnetism though—anyone got a dumbed-down example? Like, why does a changing magnetic field "create" curl in the electric field?

Also, GeoGebra’s tool is awesome for visualizing this. Appreciate the recs!
