The perturbation flow of a conducting ideal gas past a wedge-nosed plate is considered for infinitesimal magnetic Reynolds number and Alfven mach number, but arbitrary interaction parameter N, magnetic field direction θ, and mach number. The analytical solution provides the linear version corresponding to the singular behaviour of the magnetohydrodynamic boundary layer, predicted by Sears, when the flow changes from crossed-fields to aligned-fields. The factor N^<1/2>sinθ has the significant implication. If it decreases les than one for a large N, the inviscid magnetohydrodynamic boundary layer grows rapidly, but if it increases for a small θ, the flow tends to be accelerated independently of N. The solution also provides the information about the nature of the magnetohydrodynamic boundary flow on the wedge section and on the following plate section, and the difference due to the Mach number.
