The causes for the onset of a specific operating regime of MHD inducti
on devices which arises after a loss of stability of the uniform flow
are investigated. A modification of the original method of studying si
ngularly perturbed dynamical systems in the neighborhood of a bifurcat
ion point is used to construct the asymptotic behavior of the characte
ristic pressure for various limiting cases. (C) 1997 American Institut
