a) Approximating polynomial and exact function for axial field Bz(r), demonstrating the quality of fit, for λ = 0.8 (approximate, green, and exact, blue), λ = 1.4 (approximate, red, and exact, cyan), λ = 1.8 (approximate, violet, and exact, khaki). Note that only three curves are visible since the exact and approximate curves are almost identical. b) The difference between the exact and the approximation function for λ = 1.8.
