In this paper,we study the 2-D isentropic irrotational pseudo-steady supersonic flow around a convex corner for Noble-Abel gas magnetofluid.First,the properties of principal part of the centered simple wave for Noble-Abel gas magnetofluid are given.Second,by constructing the centered simple wave near convex corner,it is proved that the supersonic incoming flow can turn the convex corner by a centered rarefaction wave or a centered compression wave.Additionally,the critical angles corresponding to the arriving of vacuum and sonic state are obtained respectively.
