The stability of an infinitely long, inviscid, incompressible fluid cylinder of finite electrical conductivity in the presence of an axial current. a longitudinal magnetic field, and an infinitely long coaxial conducting sheath placed at some distance from the fluid cylinder is investigated. The axial current is assumed to be maintained constant by external sources. The effect of surface tension is included. In the case when the fluid is mercury and the axial current and the longitudinal magnetic field are of the order of a few hundred amperes and a few hundred gauss respectively, it is shown that there exists a critical product of axial current and longitudinal magnetic field which determines whether the m = 0 mode or the m = 1 mode will be manifested first in the instabilities. The results of this theory are compared with those obtained of the same geometry but with the assumption of infinite electrical conductivity for the fluid. (auth)
