Magnetic Reynolds number
text:
In magnetohydrodynamics, the magnetic Reynolds number (Rm) is a dimensionless quantity that estimates the relative effects of advection or induction of a magnetic field by the motion of a conducting medium to the magnetic diffusion. It is the magnetic analogue of the Reynolds number in fluid mechanics and is typically defined by: where U is a typical velocity scale of the flow,
Failed to parse: {\displaystyle L} is a typical length scale of the flow, η is the magnetic diffusivity. The mechanism
