The Magnetic Reynolds number is a dimensionless group that occurs in magnetohydrodynamics. It gives an estimate of the effects of magnetic advection to magnetic diffusion, and is typically defined by:
where
- is a typical velocity scale of the flow
- is a typical length scale of the flow
- is the magnetic diffusivity
