The Bohm criterion for a collisinal electronegative plasma sheath in an oblique magnetic field is investigated with a fluid model. The effects of negative ions and magnetic field on the Bohm criterion are discussed. It is shown that the parameters of the negative ions affect only the lower limit for Bohm criterion, and the external magnetic field can affect the whole range of the ion Mach number values.
