The magnetic diffusivity controls the rate of magnetic field diffusion.
Since its role in the evolution equation for the magnetic field is analogous to that of the viscosity for the velocity field, some authors refer to it as the 'magnetic viscosity'.
The magnetic diffusivity appears in the definition of the magnetic Reynolds number.
A finite value of the magnetic Reynolds number is associated with violation of Alfvén's theorem.
