We show that the scalar gradient field, \$C\$, which must be large for diffusion to operate, is strongly biased perpendicular to the magnetic field, \$B\$. This is true both early-on, when the magnetic field is negligible, and at late times, when the field is strong enough to back react on the flow. This occurs because \$C\$ increases within the plane of a compressive motion, but \$B\$ increases perpendicular to it. At late times the magnetic field resists compression, making it harder for scalar gradients to grow and likely slowing mixing
