Magnetic Reynolds number – Wikipedia

The magnetic Reynolds number (Rm) is the magnetic analogue of the Reynolds number, a fundamental dimensionless group that occurs in magnetohydrodynamics. It gives an estimate of the relative effects of advection or induction of a magnetic field by the motion of a conducting medium, often a fluid, to magnetic diffusion. It is typically defined by:

Magnetic Reynolds number | physics | Britannica.com

Magnetic Reynolds number. This number is analogous to the Reynolds number of ordinary fluid mechanics, which is used to determine whether or not a fluid flow will smooth out or become turbulent. If the magnetic permeability of free space is represented by μ0, the electrical conductivity of the plasma by σ, the plasma velocity by V,

Magnetic Reynolds number | Article about magnetic Reynolds

The magnetic field B0 is applied perpendicular to the stretching sheet and the effect of the induced magnetic field is neglected since the magnetic Reynolds number is assumed to be small and have constant physical properties.

Magnetic Reynolds number : definition of Magnetic Reynolds

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:

Magnetic Reynolds Number – ScienceWorld

Magnetic Reynolds Number. A dimensionless parameter defined by where v is the velocity scale of the dynamo, B is the magnetic field, r is the disk radius, and is the magnetic diffusivity. For values larger than , a disk dynamo is self-sustaining.

Magnetic Reynolds Number Approach – MIT OpenCourseWare

Magnetic Reynolds Number Approach • Useful for modeling eddy currents, loads and heating in dewar walls, radiation shields, vacuum vessels, etc. where R m <<1. • Two geometrically similar cases with the same R m respond in the same way, even if there are differences:
