Physics a dimensionless number, analogous to the Reynolds number, used in magnetohydrodynamics to indicate whether the dynamic behaviour of a magnetized plasma is dominated by diffusion or by advection.

M. Elsasser in Rev. Mod. Physics 22 30/2 We might define a ‘magnetic’ Reynolds number as Rm = 4πμσLv,..where as usual L is a representative length and v is a representative velocity. 1974 Encycl. Brit. Macropædia XIV. 507/2 When the magnetic Reynolds number is much greater than one, resistance effects can be ignored and the magnetic lines of force are said to be frozen to (or to move with) the plasma. 1995 Sci. Amer. Jan. 13/3 The field lines are trapped in the fluid, to an extent measured by the magnetic Reynolds number. < as lemmas |
