Magnetic surfaces and field lines in turbulence with fluctuations transverse to a uniform mean magnetic behave exactly as a passive tracer in two dimensional incompressible hydrodynamics. This broad class of turbulence models includes the two-component model for magnetic fluctuations, consisting of fluctuations having both slab and 2D symmetry. An 80% 2D/20% slab model with δB/B0~1 and a -5/3 spectral law is thought to approximately represent a snapshot of solar wind turbulence. Using this model, a recent calculation of the diffusion coefficient for field line random walk finds a functional form quite different from the standard result. This discrepancy is especially important in the small amplitude limit and affects also the theory of perpendicular diffusion of charged particles. Discussion here emphasizes the analogy with passive scalar dynamics and the nature of the approximations that lead to the new result for the diffusion coefficient.
