Abstract
A formula for estimation of a shock wave front thickness is derived from magnetohydrodynamic equations in a dissipative medium, with a finite magnetic diffusivity. It follows that the front thickness can become significant even in media - with high electrical conductivity providing that the shock speed is low enough. In the case of strong shock the effects of magnetic diffusivity are reduced and became negligible.
