WebSep 12, 2024 · To demonstrate the cylindrical system, let us calculate the integral of A(r) = ˆϕ when C is a circle of radius ρ0 in the z = 0 plane, as shown in Figure 4.3.3. In this example, dl = ˆϕ ρ0 dϕ since ρ = ρ0 and z = 0 are both constant along C. Subsequently, A ⋅ dl = ρ0dϕ and the above integral is. ∫2π 0 ρ0 dϕ = 2πρ0.
