Calculation

Local loops16
∫∫ curl(F)·dS16.0
∮ F·dr16.0
∮ F·dr = ∫∫ curl(F)·dS ✓

∮ F·dr = ∫∫ (∇×F)·dS

💡 Why it works

Each tiny loop shares edges with its neighbors. On shared edges, circulations cancel (opposite directions). Only the outermost boundary circulation survives. Toggle "Show cancellation" to see it.
